You've got to keep things fresh and competitive. People can't ever get too comfortable. Sometimes it's not the best fit for a person. In those cases (like as an employer when someone is fired or resigns), it's often the best for both parties that they parted ways. So, we don't want zero attrition. Tad Boyle hasn't had zero attrition. Not even counting NBA draft entrants, about half a roster worth of guys have left his program before their CU eligibility was exhausted. It's been healthy. That said, let's look at the roster that MacIntyre inherited and how many of these players completed their eligibility at CU. 2012 Roster (Scholarship Roster): 1. Donta Abron (RB) - still on team 2. David Bakhtiari (OL) - early Draft entrant 3. Jered Bell (DB) - still on team 4. Nate Bonsu (DL) - exhausted eligibility 5. Keenan Canty (WR) - graduated / transferred with eligibility remaining 6.

Samson Kafovalu (DL) - still on team / questions on future due to off-field troubles 35. Nick Kasa (TE) - exhausted eligibility but may have been able to get a 6th year instead of entering NFL 36. Alex Kelley (OL) - still on team 37. Alex Lewis (OL) - transferred and immediately found himself in legal trouble 38. Jon Major (LB) - exhausted eligibility 39. Tyler McCulloch (WR) - still on team 40. Marques Mosley (DB) - still on team 41. Josh Moten (DB) - still on team (possible injury retirement) 42. Daniel Munyer (OL) - still on team 43. Marc Mustoe (OL) - still on team 44. Stephane Nembot (OL) - still on team 45. Clay Norgard (DL) - still on team 46. Darragh O'Neill (P) - still on team 47. Will Oliver (K) - still on team 48. Parker Orms (DB) - exhausted eligibility 49. Juda Parker (DL) - still on team 50. Davien Payne (RB) - suspended from team following assault charge / dismissed following academic ineligibility 51. Will Pericak (DL) - exhausted eligibility 52. Ray Polk (DB) - exhausted eligibility 53. Kirk Poston (DL) - graduated with eligibility remaining 54. Christian Powell (RB) - still on team 55. Kory Rasmussen (DL) - dismissed from team / transferred 56. Austin Ray (TE) - transferred 57. Paul Richardson (WR) - early Draft entrant 58. Eric Richter (OL) - exhausted eligibility 59. Doug Rippy (LB) - exhausted eligibility 60. Kyle Slavin (TE) - still on team 61. Terrel Smith (DB) - still on team 62. Justin Solis (DL) - still on team 63. Nelson Spruce (WR) - still on team 64. John Stuart (DL) - transferred 65. Gerald Thomas (WR) - transferred 66. DaVaughn Thornton (TE) - graduated with eligibility remaining / transferred 67. K.T. Tu'umalo (LB) - still on team 68. Josh Tupou (DL) - still on team 69. Chidera Uzo-Diribe (DL) - exhausted eligibility 70. Paul Vigo (DB) - exhausted eligibility 71. John Walker (DB) - still on team 72. Kyle Washington (LB) - medical retirement from concussions 73. Derrick Webb (LB) - exhausted eligibility 74. Jordan Webb (QB) - exhausted eligibility 75. Lowell Williams (LB) - graduated with eligibility remaining 76. De'Jon Wilsom (DL) - still on team 77. Alex Wood (FB) - exhausted eligibility 78. Connor Wood (QB) - graduated with eligibility remaining 79. Yuri Wright (DB) - still on team That's 48/79 that are either still on the team or graduated with all eligibility exhausted. That's attrition of 39.2%. I think this is where statistics lie. If I saw a newspaper article titled "CU football attrition rate of almost 40% since MacIntyre took over", I would criticize the article for being negatively slanted. Many of the players in that number graduated. A couple others went to go get paid by the NFL. A couple others had serious injury issues. And there were also some family reasons. Beyond that, there are only a handful of guys who didn't complete their potential eligibility that would have clearly made the Buffs a better team had they stuck around. In short, MacIntyre has largely turned over this roster but done it in a way that allowed guys to graduate and tried to save a number of players that have had off-field issues (behavior and/or academics). We have had attrition, but not necessarily "bad" attrition. The other way of looking at this is in terms of the players that have been recruited since MacIntyre took over. For the 2013 recruiting class + transfers, the following players were added to the program: 1. Michael Adkins (RB) - still on team 2. Chidobe Awuzie (DB) - still on team 3. Bryce Bobo (WR) - still on team 4. Connor Center (TE) - still on team 5. Timothy Coleman (DL) - still on team 6. Elijah Dunston (WR) - still on team 7. George Frazier (FB) - still on team 8. Jordan Gehrke (QB) - still on team 9. Jimmie Gilbert (DL) - still on team 10. Diego Gonzalez (K-tnfr) - still on team 11. Gunnar Graham (OL) - decided not to play football 12. Jonathan Huckins (OL) - still on team 13. Gerrad Kough (OL-gs) - still on team 14. Sam Kronshage (OL) - still on team 15. Phillip Lindsay (RB) - still on team 16. John Lisella (OL-gs) - still on team 17. Sefo Liufau (QB) - still on team 18. Derek McCartney (DL-gs) - still on team 19. Kenneth Olugdobe (LB) - still on team 20. Markeis Reed (DL) - still on team 21. Deaysean Rippy (LB-tnfr) - still on team 22. Devin Ross (WR) - still on team 23. Ryan Severson (LB) - still on team 24. Colin Sutton (OL) - still on team 25. Jeffrey Thomas (WR-gs) - transferred / academic and off-field issues 26. Tedric Thompson (DB) - still on team In his first year, MacIntyre brought in 26 guys. 24 of them are still here for Year Two. That's 7.7% attrition for that group. If anything, that number is lower than ideal. If you figure a recruiting class has 25 guys, a program would end up with 125 guys on scholarship if everyone redshirted and stayed in the program. Obviously, that doesn't happen. But let's say that you have 15 redshirts and then 4 other classes on your roster at any given time. (From that 2013 group, 16 redshirted last year). That leaves us with 70 guys on the active roster for 4 classes (Sr, Jr, So, Fr). If you bring in 22 guys a year and have 10% attrition, the numbers would shake out as follows: Freshmen: 22 Sophomore: 20 Junior: 18 Senior: 16 That totals to 76 guys, so with the 15 guys redshirting we at 91 and are still above the scholarship limit of 85. 22 guys with 15% attrition yields the following number: Freshmen: 22 Sophomore: 19 Junior: 16 Senior: 13 That totals to 70, so with the 15 guys redshirting we are right on the 85 limit. Modifying this is that you'll want to bring in transfers from JUCOs and other D1 programs to backfill your upper class holes that develop through this normalized attrition rate of 15%. That way, you end up with the 85 players, but more of them are in the upper classes versus if you only brought in freshmen every year and had this attrition rate. Through the transfer market, the Junior and Senior classes will have closer to 20 guys. Also, by the time that the season rolls around there has usually been some late attrition that results in senior walk-ons being awarded scholarships to bring the total to 85. That often results in the Senior class being larger than the Junior class by the time the final roster for the season is set. Currently, CU's football roster with class breakdown looks as follows: Freshman: 30 (14 already redshirted) Sophomore: 24* Junior: 15 Senior: 17 *Note: assumes Shane Callahan (OL) has joined team as a sophomore transfer. Senior class may reduce by 1 if Josh Moten (DB) medically retires or Junior class if Jeffrey Hall (DB) does not find his way back from legal issues or Samson Kafovalue (DL) isn't able to stay on the team or maybe something else to get down to 85. When you compare the actual roster numbers to the normal 15% attrition rate, the Buffs are actually about where we would want to be in terms of class balance. Junior class is a bit too light and this is still a young team. However, the numbers are about right and it's getting there. But through retention of the guys brought in during Year One (2013 additions) that saw half the normal attrition rate and some strategic use of transfers, MacIntyre has been able to work with attrition of almost 40% from the roster he inherited 2 years ago and maintain pretty good class balance. Going forward, we don't want to stay at 7.7% attrition. We need that number to be in the 10-20% range for things to be at their healthiest. But retention was absolutely called for this past year and helped to normalize the roster. Also, it looks like with such a small senior class in 2015 (barring graduate transfers), it will take until 2016 before MacIntyre has a completely normalized class balance with upper classes full of guys who are here because they bought in. Almost all of the element of any team that are on the roster because they used their golden ticket, got comfortable, and were able to stick around for 4 or 5 years will have been weeded out by then. There was a lot of that element in CU football in recent years. In conclusion, I believe that roster turnover has been handled well by MacIntyre. We have had attrition where we needed it, but not so much that it crippled the talent level or team morale. Both attrition and retention has been very strategic, as has the use of the transfer market. I see a lot of moves that show me a coach doing what he can to win now by bringing in transfers and coaching up players he inherited instead of going with a youth movement. At the same time, I see building foundations for a sustainable future by keeping the roster balanced on class sizes. And it looks like this roster will be better set up in 2015 than 2014, with 2016 the year we finally see a roster at CU that looks like it should.
