It certainly wouldn't hurt his status, IMO, Iowa goes 7-5 this season, is just average... the narrative here and nationally will be Stanley is just not that good. Not ready for the next stage. If Iowa wins 10 games, wins the west, they play in Indy and go to a big bowl - the exposure and narrative will be... look at this kid, he's a winner, a total gamer who is going to play on Sundays.
Either way some of these mocks (who i've stated is not really a great resource and they are guessing, but it's all we have) have him close to the 1st round as is. It might not take a 10 win season. We just don't know because NFL GM's don't really offer up their thoughts.
