Edge has this bad rap that he's just a system back and was only along for the ride aboard the Peyton Manning Experience, when people forget that many times he was the one carrying that offense. How the Colts ran him into the ground from jump street is the reason for his early knee injury that robbed him of his home run ability. Without his ability to take it to the house, he adjusted his game and still performed at a dominant level for six years.
He's one of the best modern backs of all-time and it's sad that he doesn't get proper due he deserves because of perception and circumstance. In the end, his HOF status hinges on Curtis Martin.
I guess to me, only "the best" modern backs of all time deserves to make the Hall of Fame, and not necessarily "all of them."
Curtis Martin, IMO, makes a better argument. He was covted by two of the best coaches of the era in Bill Belicheck and Bill Parcells. He excelled for two different teams, and carried their offenses at times. Also, he lead the NFL in rushing at a remarkably advanced age and rather unexpectedly.
By no means do I think that Manning "made" James. In a lot of ways, I think that they helped each other. But James was a guy that essentially no one wanted when he became a free agent (I think the Cards were negotiating against themselves three years ago), and his production dropped off precipitously.
I don't think that any RB could succeed in that situation, and I think Edge is a gamer and a great guy to have in the lockerroom. But I'm conservative about the HoF, and I mainly feel that if you have to make an arugment for a guy, he probably doesn't belong there.
For me, Marshall Faulk is in, and Emmitt Smith, but I might not let another RB into the HoF until five years after Ladanian Tomlinson retires. Probably Curtis Martin, probably not Tiki Barber.
