Frank Gore had an entire yard more per carry than Parker and Jackson and more than that against Johnson (both of them). I'm not sure what metric you're using to determine that ranking, but I'm looking at the big picture here. 5.4 yard per carry is really, really fucking good. Gore had the third most rushing yards that season behind LT and Larry Johnson (Larry Johnson had over 100 more carries that season by the way). Only four RBs were averaging 100 yards per game and Gore was one of them. Next to LT, he also had the most amount of big gain plays.
Facts, not opinions brah.
