Dolphins wide receiver Brian Hartline did his best to avoid answering a question on NFL Network Wednesday about if teammate Lamar Miller is a 25-carry-per-game running back.

"Luckily, at this point in my career, I don't have to make those decisions," Hartline said, per NFL.com.

Although Miller has started all five games for Miami, he hasn't had more than 14 carries in a game and has 50 carries to backup Daniel Thomas' 27 carries.

"I would say our coaches are really wanting one of the guys to step up," Hartline said. "You want someone to take the bull by the reins, and the coaches feel like that hasn't happened yet. So, until that happens, we are going to see multiple guys coming out of the backfield."
