*I'm not counting 2008 Big East as a P5...once Miami left, it was a glorified Conf USA
There's also...
2005 Reggie Bush (1700 yds @ 8.7 per rush w/ almost 500 yds receiving)
2002 Willis McGehee (1700 yds @ 6.2 per, 28 rushing TD)
2006 Steve Slayton (1700 yds @ 7.0 per, 16 TD)
Mike Hart, Wiliam Green (BC),...McFadden's ypc are more pedestrian than I thought (5.8, 5.6).
2009 Mark Ingram (1600 yds, 17 TD)
I'd need 4 if I have a statue at QB, or only 3 if I use Tebow/McCoy.
