You don't quite get it? I'd rather draft a guy who doesn't have an ACL jnjury history, and "could need another surgery there" in the future. And Fautanu will be already be 24 years old in October, so I'm sorry, the potential of throwing away a full season of a first-round pick in his prime doesn't sound very appealing to me.
As
@slashsteel said, there's nothing we can do but wait and see. What I have noticed is that even on all the clips of Penix, I've been watching #55, and he seems to be doing an excellent job fundamentally on just about every play. So I understand what the Steelers like about him.
