I doubt Curry will turn out to be a bust, but he's not a fan-favorite either. He's already gained a reputation for being a dirty player and he's displiked by players around the league. I think he had a pretty good rookie season. He wasn't healthy the whole season, so his production wasn't spectacular, but he's talented and a good addition to the Hawk's defense.
He'll probably turn out to be a very solid player for them, but I don't know if he'll every live up to the hype a #4 pick gets. That's not entirely on him though. He's an OLB. He's not going to win games for them.
Unless Suh comes in and just dominates, which is highly unlikely, many will consider him a bust also. That's just the nature of his position. I'm sure fans are pissed at the Chiefs for Dorsey and Jackson, just as Saints fans aren't thrilled with Ellis.
