The real question is does he have enough gas left in the tank to catch Emmitt Smith 3,607? At 4.0 a carry that’s about 902 carries. Probably won’t happen, but assume he comes in 2019 and has a throw back year - 1,400 yards. Then perhaps 3 more seasons at 750 yards (age 37-39) and he’s in the record books. Sounds about as crazy as a 42 year old who is arguably the best QB in the game. Sports medicine and science has improved & behind a dominant line it could be a history making next 4 seasons for a guy known for being a decisive one cut down hill runner.
