To my knowledge the signing period does not end Friday, it is just entry into the portal for all teams except IN and Miami, whose players have additional days to enter. Players in the portal can and will sign later, but it does get tricky for players desiring to enroll in school for the spring semester. Probably, most programs and CU may have a work around on this. A few schools are on quarters. Plus, if there are new HCing coaching changes, I think it is still open season on those rosters... The coaching carousel should be about closed, unless a college coach jumps to the NFL. I think we will see signings into early Feb. For players that do not enroll in spring, they miss Spring Football but I think they could still sign and enroll in summer school. These players would be at a disadvantage since they would not be part of S&C, nutrition, medical, and football related areas.
Based on what John wrote yesterday, I concur that we are probably looking at 10-15 more transfers to complete a decent roster. There are still a bunch of good players in the portal and maybe some great ones. I think CU may take even more guys to fill out the roster if they want to get anywhere near the schollie limit.
