That 2628 is just a mind-boggling total.
Russ Smith said:The list I found is from 2003 so it's not current but:
Barry Sanders 2628 1988
Marcus Allen 2341 1981
Troy Davis 2185 1996
LaDainian Tomlinson 2158 2000
Ricky Williams 2124 1998
Byron Hanspard 2084 1996
Rashaan Salaam 2055 1994
Arrington had 2018.
I found them in PDF and so small I have to print the page to see what's on it so I don't have the YPC numbers but I doubt many of those guys on the list are much higher than 7YPC.
Sanders and Allen were all time greats, Davis, Salaam and Hanspard busts, LT looks like HOF, Ricky was damn good before he retired.
So 4 worked out really well and 3 didn't.
