This gets at the heart of the whole thread I think. You don't find Marshall or Boldin deserving of their rating because they have an
"RBlike" rating in one of their columns and yet they aren't RBs. But really that is like saying that Seneca Wallace and Brian Westbrook shouldn't have their CTH and RTE ratings where they are because that makes them better than some legit wideouts. Or WR Brad Smith with his Leinartlike Arm or Flaccolike accuracy.
Players can and do excel in areas typically reserved for other players traditionally. Devin Hester is playing WR now, Hines Ward can hit like a safety when he gets the chance, and a basketball player like Antonio Gates can convert to playing TE in football.
I think one of the biggest problems is comparing all of this to Forte. I know he is the back most familiar to you and you naturally went to check his stats for comparison, but there are 40+ HBacks that truck better than him. Which means there are about 40+ Hbacks that truck better than Marshall. There are only 32 teams in the NFL...
Is it that unreasonable to think that someone outside the running back or TE position should have a high truck rating?
Anyhow, the argument had pretty much been made before I got here, but I found the thread interesting and amusing enough to throw my 12 cents in. If the enormous amount of evidence posted by numerous contributors contrary to your position isn't enough to settle this for you, (nobody really came to your defense - I DID read the entire thread) nothing will.
