K I do have to say it's a fairly safe opinion. If you play the odds, most QBs don't end up "the man". Most teams are struggling through with an adequate (read that to mean "disappointing to the fans") QB. How often does any team feature a "knock your socks off" QB? Rarely. The rest of the time everyone is making due with Jordan Jeffersons and Joe Coxs and Jevan Sneads and Greg McElroys. Hell even LSU and Georgia struggled with first round NFL draft picks behind center.
Add to that the fact that people were excited to get Rollison and expect him to do well, and well, you're opinion isn't so much based on anything other than the odds along with your lean towards pessimism. (you're probably saying "duh" so far).
However, keep in mind that Chris Todd just set a lot of QB records at Auburn. Rollison may only need to be Jordan Jefferson-esqe or Chris Leak-like in order to lead our offense to great things. He may not need to be the rare Vince Young, Tim Tebow, or Pat White in order to meet expectations. I for one am not expecting him to be a Heisman candidtate. I am expecting him to help us win games.
I think it was Coleman who was extremely impressed with him during pre-season scrimmages. He said he was calm and confident and ran the offense like a veteran. For a senior defensive player to have that praise for a true freshman was encouraging to me.
