No, I wasn't impressed with results against Lawson, Teague, Henderson and Dwill just to name a few. Give him credit for the effort but that's the only thing that separates him from other top guards in the league.
Williams and Henderson can bully him. Lawson and Teague can match or exceed his quickness.
That's the key with Bradley; you have to be able to match or limit his athleticism somehow. In the case of quick guards like Lawson, he needs to learn to play an extra half-step back. It'll help him shut off the drives, and I believe he still has the length to contest shots. But there's no easy fix for guys like Williams, who can just muscle through him and get him in foul trouble.
It's important to note that guys like Williams, Joe Johnson and DeRozan are capable of scoring on anybody. I'm also firmly of the opinion that people would know Gerald Henderson's name if he played anywhere but Charlotte. So the fact that they played well on his watch (though I don't consider the Henderson explosion to be primarily his fault) isn't really an indictment on Bradley... they're just really good.
