"We've got to break more tackles. I may have been guilty of overcoaching, harping on the ball security issue," Philbin said of Miller, via The Miami Herald. "He really did a good job of that. At some point, running backs need to break tackles.
"It's not that he didn't break any. But he's got to break some more. There is room that we could potentially utilize him more (as a pass receiver). He has good natural hands, good speed."
This is no small hurdle for Miller to clear.
