Espy has been hurt since he was added to the team. I don't think he is durable enough.
I am high on Mix, but only because all my Giants friends are mad at me that we signed him. I would like to see what he can do when given an opportunity to play, especially with his old college QB throwing. He never got the chance to play at WR for us yet alot of people say he can't cut it. They base that opinion on what, exactly? He was great on teams too so that alone should keep him here.
I think that Mix's practice work ethic was in question when he was in college but from what I have read, he worked hard for the Giants and I know that he made big plays for us on special teams so I think that he should get a shot. I just hope that after he gets that shot that he does not take it for granted and regress back to the same habits.
