Let’s face it, Miller is a first- and second-down back. He usually won’t be in the game on third downs.
Daniel Thomas is the third-down back. He’s a better pass blocker, receiver, and short-yardage runner.
Plus, you’d expect quarterback
Ryan Tannehill to pass more frequently than a year ago with new toys such as wide receivers
Mike Wallace and
Brandon Gibson and tight end
Dustin Keller. That’ll cut down Miller’s carries.
Beyond that, the offensive line is shaky, which also works against Miller. You’ll recall Miller was slowed by nagging injuries in college. He has to prove he’s durable enough for a 16-game NFL season as the primary ball carrier and a leaky offensive line won’t help in that regard.
Miller has the speed and moves to be an effective back in the NFL, but so do about 30 or 40 other guys. Miller has to prove he’s an effective ball carrier.
The best way to judge Miller is to look at his yards per carry, and if he’s around 4.3, and he stays healthy, it’s been a fairly productive year.
