Citing Larry Johnson as your example Belvis is kind of Fake Sugar Dick (WARNING, NOT THE REAL SUGAR DICK!). The guy ran for 2100 yards his senior year, was a heismen finalist, was drafted in the first round, ran for 1700 yards in back to back years, and played 8 years in the league. Oh and he's not in his prime. He's 31 years old and is a running back. If anything he actually proves that if you can really run the ball, then you can still be a pretty effective back if used right. And I really don't think blocking and all of the other things that go into being a complete back are not important. My issue is with the people who have concluded after 8 plays that Bryce can't do anything, but run the ball. Maybe that's true, but until we actually get some kind of a sample size then it's hard to draw a conclusion either way.
