This is a win/win. We get a QB with some familiarity to Mac's system, has some game experience, and can compete. We lose dead weight at the QB position after the spring. When those guys are gone, that frees up scholarships in which one can be given to Fishback.
We already know what we have. Mac didn't recruit any of these guys so there is no loyality to make sure they work in his system. Webb is done in that he has alreay graduated and we don't have to give a scholie for next season. Wood should transfer if he ever wants to play QB, it will have to be at the D2 level somewhere in Texas. Dorman should get the news soon and move on as well. It doesn't hurt to keep Schrock around.
Our team will be better with Hirsch, Shrock, Dillon, Sefo, and Fishback on the team and with Dorman, Webb, and Wood gone. And we don't need them to switch positions. Don't need another slow small WR in Webb who already has a bad hand. Or a slow Dorman at Safety.
I'm glad that Mac is looking to make moves. It is time to clear out those that don't fit into this system and continue to improve the team.
