Why am I not surprised you made some BS attempt to downplay that list. All you have done is shown just how much of a football noob you are.
Really? 3,4,5,6,7 and 12 are extremely well known RBs to anyone who has watched football in the last 20 years. . But yeah.. Not consistent or long career.. Out of that entire list, Only Eddie Lee Ivery was someone I had to look up.
Deangelo Williams - 11 years - 96 starts out of 142 games
Maurice Jones Drew - 9 years - 71 starts out of 126 games
Fred Taylor - 13 years - 137 starts out of 156 games
Brian Westbrook - 9 years - 90 starts out of 121 games
Tiki Barber - 10 years - 109 out of 154
Herschel Walker - 12 years - 137 starts out of 187 games
Eddie Lee Ivery - 8 years - 50 starts out of 72 games.
Heck, Napoleon Kaufman may have only had a 6 year career, but he accomplished the feat twice.
