I think that Richt probably does want JW to win the job, but with him not arriving until the summer, unfortunately it seems he just didn't feel like he was ready to step in to what seemed to be a team that was pretty experienced and ready to win now. I'm not saying that I agree with the choice of mediocre experience over the potential for good/great decision, and I don't think anyone knows if the thinking would have been different had we opened with Savannah State rather than LSU, but I've got to think that the opponent weighed heavily in the choice.
I think his choice of Rosier last season was based on Perry not getting to school until the summer, and then once things got going, it was tough to justify pulling Rosier, and burning Perry's RS. This season, from all reports, it sounds like Rosier was significantly better in practice, and maybe that Weldon and Perry weren't getting it done off the field either. While I think it is important to reward practice performance to a degree, so that you do have guys performing in practice, I think that at this point, it's clear that the practice Rosier is not the game Rosier.
I don't see how Richt will be able to continue to justify keeping Rosier on the field and these young guys off. Our QB is completing passes in the 40% range. He is not just killing us with his lack of accuracy, he's making terrible decisions with the ball, resulting in brutal turnovers. He's missing wide open WRs. He's pulling the ball down and running if his first read isn't there and creating pressure by breaking from the pocket prematurely. He's not allowing our guys to catch the ball and make plays afterwards. And, assuming the reports are true about guys in the locker room being understandably unhappy with his play, the guy who is supposed to lead our team has lost the faith of our team after 1 game this season. Rosier isn't Richt's guy, he's doing all the things that drive Richt crazy, and we have 3 young QBs who are available. It's time to give all of them a shot to step up and lead this team.
