Cardinals coach Bruce Arians expounded this week on his plan to build the offense around second-year running back Andre Ellington.
"He is still not a guy who you will pound up the middle 30 times a game and survive," Arians said at the NFL owners meetings. "He can run the football 30 times a game if you do it correctly, but you'd rather have him have 10 catches and 20 carries and let Stepfan Taylor or (Jonathan) Dwyer have the rest of the carries."
As excited as he is about Ellington, Arians said the offense must be diverse.
"You've got to watch that you don't create too much stuff and then he sprains an ankle and you don't have any offense because you put too much in one basket," Arians said. "You still have to have your cinch-it-up, grind-it-out football.”
