Scouts -- and Raiders coach Tom Cable -- agree that McFadden and Bush are different backs in just about every respect.
Two scouts believe the 6-foot-1, 245-pound Bush is too intriguing to pass on as a lead back. They point to his size, build and determination. And his perseverance through two surgeries on his right leg, one that caused him to sit out his entire rookie season in 2007.
"You're talking about a guy who is built like a fullback, runs like a 220-pound running back and gets better as the game goes," an NFC scout said. "I tell you what, that's not the guy you want to see coming at you in the fourth quarter of a game after three quarters of wearing you down."
Scouts agree that Bush doesn't excel in any one area, but he doesn't have any glaring flaws, either. And he stands out over McFadden in his ability to break tackles.
Rumors persist that Bush will be the 1st and 2nd down RB while Mcfadden is utilized on 3rd down or 2nd and long.
