It's hard to argue with the facts. Older QB make a difference, even if they are just game manager types, as those.
The wildcard is what if you have a young super star, who is beyond his years and not a game manager??? KR could be that type of QB, but he'd come with growing pains as he learned.
But, if we bring in a transfer (who I don't even know) TS, who could be a star himself, is likely gone and that loves us with the true freshman as the only legit QB on the roster.
If Arch Manning, who Archie said is better than both Eli and Peyton were at that age, couldn't wrangle the starting job away from Ewers. I'm going to go out on a limb and say, Russell, though very talented, isn't going to be able to step on campus and slide right into the starting role at Alabama. If he has to start it will be more of Simpson is just a bust than Russell is that good.
