4,51 is the best time for any 240 and up RB in several years. Dalvin Cook at 213 ran 4.89 and 202 pound McCaffery did 4.88
There is entirely too much stock put into this 40 time bullshit.....Emmitt Smith ran a 4.7 at 216 lbs. He had a pretty good career..Charles Haley, first of only TWO NFL athletes to have 5 SB rings, ran a 4.7.. Tom Brady ran a pedestrian 5.28, he's had an OK career......Two are HOFers and the other is definitely a first ballot HOFer....Understand that there are 13 SUPERBOWL rings between those three SLOW fellas......
