See Gailey & his 2008 class. I think a lot of people knew the 2007 class was going to be VERY promising (Dwyer showing out early, Nesbitt contributing in a "changeup" QB role, DJ Donnley contributing, Morgan Burnett making plays, Derrick Morgan contributing), and his 2008 class was shaping up to be a pretty decent class...not 2007 level, but pretty good compared to his past classes with Sean Renfree coming to be the QB GT was missing during Gailey's tenure.
Point is, AD's don't make coaching decisions based on recruits and the roster situation. Those things ebb and flow, but if an AD can get a good coach in, the belief is that coach can change the complexion of the program for the long run (see Bobby Ross, George O'Leary). At the end of the day, CPJ's ultimate fate will rest in how many wins, $$$ from big donors, and attendance. Gailey wasn't fired because he was losing, in fact he never had a losing season, but unrest from the fans and big $$$ donors unwilling to give money until they got their return on the field ultimately lead to Radakovich cutting ties and CPJ today. There's a lot that goes on behind the scenes beyond just wins and losses. It won't be just Bobinski making the decision.
I think Bobinski has been pretty clear about a two things: He will not accept mediocrity (mediocre defined by him is ?), and he will not accept excuses regardless of GT academics. He's made those points in several interviews. Read into that what you will, but it's pretty obvious he's giving CPJ all the tools he can to succeed (larger recruiting staff, larger recruiting budget, enhanced media presence, etc.) and he expects results commiserate to those investments.
This season will be more interesting in more ways than what happens on the field.
