Wallace so far has been a huge over paid disappointment. When it's not Ryan not throwing the ball well to him, he drops them when they are accurately thrown to his direction. Guy doesn't seem to hustle for most plays. Very frustrating to say the least.
I think this is a HUGE reason the Steelers let him go, he was very good with the Steelers, when he wanted to be, it also helped that he didn't have to do it all, they had 3 good WR's going at the time ... Sanders, Brown and Wallace, the year before, they gave Brown the big contract instead of Wallace.
