This is a tough one. Edge is Dubbed the only player in the league without a weakness. And this lable comes from the big guns on the panels, John Madden being one of the people who has said this.
Now with Brown, we get the same kind of guy in terms of being very able in pass protection, and a guy who can catch and run. Edge is really in a league of his own though. His running style is so unique. He never takes a big hit, always gets his man on passing downs, and averages around 5 per carry. I think that Brown definatly has a chance to be great. Putting on teh same level as Edge right now isn't fair to him.
The numbers will do all the talking, that being said, if Brown even comes close to what Edge has done so far, we have really picked a gem.
