Stepfan Taylor and Jonathan Dwyer will have distinct roles

Although Stepfan Taylor has been running ahead of Jonathan Dwyer in training camp, Cardinals coach Bruce Arians said the running backs are not competing for the backup role behind Andre Ellington. Instead, Arians plans to use each back based on his strengths.

"We have all the confidence in the world in Stepfan and Jonathan," Arians said. "Jonathan had a big, long run (Tuesday) and Stef did an unbelievable job in pass protection. It’s an ongoing thing, and we’ll use them both.

"We won’t really have a two and a three. They’ll have roles and go into games with roles so everybody knows exactly what to expect. And when your number’s called to increase your role, you better be ready."
