I look at it like this - Will is kind of like Mullen starting out having to play Tyson Lee. Tyson was a great leader, a JUCO All-American, but he wasn't necessarily SEC QB material and wasn't a perfect match to Mullen's system.
But, Tyson was all we had until Relf could get ready. Will is matched to the system better then Tyson was, but at this point in his career I'm not sure Will is SEC QB material. But, like Tyson, at this point he is the best we've got and 1 of 2 things will need to happen - either A) Will advances or B) someone progresses and beats him out. If A happens great, we win more games. If B happens, great we win more games. If neither happen, it will be a long couple of years.
