I'm not a giant fan of the move because we have so little space in our upcoming class already and have a number of positions that have to be addressed in recruiting for the team to be successfull.
At the same time I wonder a couple of things.
For those here who are critical of Webb (can't throw, to small, etc. etc.) are you assuming that the staff didn't take the time to evaluate if this kid could contribute at this level.
Also is the entire backup QB position a disaster. Dorman has by all reports been a major dissapointment, Schrock has been a pleasant surprise for a walk-on but he is still a walk-on, Dillon gives reason to be excited for the future but even if he didn't need to bulk up significantly and develop strength he would be a true freshman, since he is looked at as the future it is best to put another year between him and Wood.
This all means that if something happens and Wood can't play you are left with Hirschman as your only back-up who is ready to play meaningful down. The same Hirschman who has broken both feet in the last year and who plays a style that usually ends up with him getting hit and hit hard frequently.
To me this move means a couple of things. One is that the coaches believe that we are at a point were we can be winning meaningful games and they don't want to risk playing a back-up who they don't think can compete in meaningful games. It also means that they have a plan for Dillon and don't want to pull a Hawkins and destroy that plan by burning his eligibility without reason.
It may also mean that they are not sure that Nick's feet will ever let him come back and be a dependable player for them. Feet are medically a very sensitive issue. We put all our weight on a bunch of small bones that have to work together perfectly not to hurt or to put enough strain on another bone to break it. Knee injuries get a lot more attention but plenty of careers have been destroyed by bad feet. The coaches may have seen enough with Hirschman's feet problems to decide that action needs to be taken to protect themselves.
