Curtis Martin part of Dying Breed? After Tomlinson then what?

Is this the next to last Running Back to ever be enshrined in the Hall of Fame?. Its a good question to ask considering the position is being fazed out of the sport to the degree that a RB cant even dare ask for a pay raise. Will Adrian Peterson and Maurice Jones Drew even be allowed to accumulate Hall of Fame level stats? and if they do will the current culture of the NFL go against them when that door closes and the voting begins?. I believe when something is close to extinction it evolves, in other words i have a sneaking suspicion that what Rex Ryan and Tony Sparano want to do with Tebow is the next phase of the RB position. The "Wildcat" is a trend but the multi threat Running Back is viable and hard to game plan for. The last Heisman Trophy winning QB to play RB in the NFL was Paul Hornung and Lombardi used him like an all purpose Swiss Army knife. Hornung threw passes, ran the "Packer Sweep" from the tailback and fullback position, caught passes, punted and kicked field goals all the way to Canton. Just watch any of the Under Armour High School All Star games, the Position "Athlete" is already allowing coaches to be more creative with their recruiting pitches and game plans- and don't get it twisted, if the kids didn't think it was cool they wouldn't permit it. If Tight Ends can evolve into Basketball players and arguably the best Athletes on the field then RB's may look like Tebow in the future. Remember Marcus Allen was a High School QB, played Fullback during Charles Whites Heisman campaign and could catch the ball in addition to being a great runner.  LaDainian Tomlinson will be a cant miss HOF in 5 years and even he could pull it back and go deep, when i look at Tebow all i see is Mike Alstott with a spiral- and for the record i'll take it.
