Just to expound on how non-equivalent the Bush/McFadden parallels are:
1. Bush played in the most dynamic offense in college football, behind great offensive lines, and ith a QB and receivers who filled the first and second rounds of the NFL draft. Can you say that about anyone on that Arkansas offense, aside from Felix Jones? I don't know about their Oline, but is there a single day 1 prospect on that side of the ball with McFadden? There is nowhere near the talent surrounding McFadden that surrounded Bush.
2. Bush played in the defensively undermanned PAC-10. Surrounded by playmakers, Bush got to go up against slow, stupid defenses week in and week out. McFadden has to go up against teams stacked with NFL talent week after week - and he still produces.
3. Bush never played the feature, carry the load back role for any period of time at USC. McFadden is given the ball 30 times a game sometimes, and never slows down despite the brutal beating he is taking, because he runs so tough.
So please, stop the inane Bush-McFadden comparisons just because McFadden is so physically superior that noone can get an angle on him - even in the SEC. The only thing they have in common is their speed. Bush is nowhere near the overall physical specimen that Darren McFadden is, and he will never be the RB that McFadden will be.
McFadden = Sure Thing. Don't sleep.
