We've been spoiled by first round QB talent the past several years prior to Milroe, so when we have a QB that's pretty much like a usual SEC level QB, we can't take it. For years we ate 2 dollar steak at the QB position, so when we got a taste of the prime ribeye, we didn't want to go back.
Milroe is fast, there's no doubt about that, but he seems to lack the instincts to make him a natural running back. There was a play I saw during the Tennessee game where it looked like he had the blockers leading the way, but, for some reason he kept going laterally instead of cutting up field.
Milroe can also make some amazing throws that make you think "Wow, that was a great throw". But, there's also so many plays during the game that occur that make you think "Wow, what was he doing there. Or, how did he miss that throw?"
