The NFL is morphing into a running back-by-committee league, with the average number of attempts per season for top-10 rushers falling from 338 in 2006 to 280 last year.
"I can tell you this, I believe in the (bell cow). And I believe it's up to the player to prove he can do that. Do you need two guys in a season? You are darn right, in this league," Kubiak said Tuesday, per the Denver Post. "But I think if a guy goes out there and he shows he can play three downs, can protect the quarterback, and can handle it, then he should stay out there."
Kubiak's history backs up his statement. His zone running system in Houston and Baltimore coaxed big years from Arian Foster, Steve Slaton and Justin Forsett. Foster led the league in carries in 2012 (351). Slaton and Forsett -- not exactly viewed as workhorse backs -- each cracked the top 10 in 2008 and 2014, respectively.
"He has told us if you get the chance and play well, you will stay out there. My goal is to be out there all three downs," Anderson said. "That's my plan."
