Not that 40 is the most important metric for a RB but it is relevant. I have broken this down into weight classes for easier comparison. A couple of times stick out like a sore thumb. Fournette running 4.51 at his weight is the most amazing 40 time on the chart. James conner is damn fast for 233 pounds, as well. Logan and Cohen both had super fast times. Cook was 1st in his weight class. Kareem Hunt was dead last in his weight class.
