The Arizona Cardinals sit in an enviable position, with three running backs who, when healthy, could be starting.
"David's earned the right now to be the bell cow," Arians said, via ESPN.com. "Everybody's got to take it from him. But Chris ran for 800 (yards) and probably would have had 1,200 had he stayed healthy. Andre can break the game open."
Chris Johnson's return -- for less money even -- was somewhat a surprise (and a testament to Arians), because it was blatantly clear David Johnson would get a chance to be a three-down back. Just 24, the second-year back has rare skills to be a between-the-tackles runner, speed to get to the edge, vision on the second level and is very good in the passing game. Of his 581 yards, 442 came in the final five games of the 2015 season. He also added 216 receiving yards over that five-game span.
Chris Johnson should be insurance if David gets dinged and Ellington will provide a home run threat.
"It's fun to have those guys back together," Arians said. "Andre's healthy. It'll be a great competition in our backfield this year."
