In all fairness, Greg McElroy was 24-3 in his time in Titletown. Didn't make him a great college QB. If Jalen goes it seems he is leaving as a graduate transfer. For me, not great news, but much more emotionally acceptable that those who leave early because they don't want to compete.
If Tennessee is going to run a pro system, and you are, why would Jalen be a good fit? He ran out of the pistol most of the time last season and frankly, didn't have near the production he did as a freshman under Kiffin and the spread RPO system. Unless Helton is going to do something different than what he said he was doing at Tennessee. He said, run, run, run and be a big play offense. So he wants to play ball control and go long. Sounds like he learning toward strong-armed, pro-style guys.
