Braylon is virtually a rookie (considering the limited play he got last year because of injuries) and he is already contributing at a high level on a mediocre offense.
He gets (and will continue to get) tons of looks, as CLE will often play from behind and he is the only legit WR threat. Even if JoeJ comes back, he'll still be integral in the Offense. If anything, his coverage will soften a bit.
I watched Braylon all through college and I can tell you a few things. The knock on him that he drops a lot of balls is fair, but a bit overstated. I wouldn't worry about that. The thing that makes him great is that, except for Randy Moss, I have never seen any WR at any level catch the deep ball as well as Edwards does. Whether its catching it while streaking down the sideline, or going up for the "up for grabs" ball, he has that uncanny ability (like Moss) to come up with the ball.
So, for Fantasy Football, if you have a guy that gets 8-10 balls thrown at him each game and has above average ability to score long TDs and plays for a team that has to pass a lot to come from behind... those are the ingredients for a top 10 WR.
