I don't make 7 figures but i sure in the hell wish I did and I'm not connected enough to any team to influence a decision.
I'll address you questioning of his "hunger" and say any player that is the first on the practice field, first in the weight room and first in the meetings and the last to leave, team captain, labeled as one of the hardest working players by a long time coach like Joe Paterno who have seen many come and go do not have their "hunger" questioned. He has a passion for the game and desire to be better that will be hard to match.
As far as his play, he has everything you look for in a offensive lineman. Good feet, technically one of the most sound players in the draft, smart, finishes blocks, nasty, good bend and gets to the second level.
There is a reason he is in the mix to be the #1 overall OG in this draft. In the end I think Pouncey get's taken first but many scouts will admit the gap is not that big.
You can't watch a handful of plays from a couple games and base a decision on it. I'm sure what ever you do in life you don't have your best day every day, every moment your doing it.
