Miami Dolphins running back Lamar Miller is still the top back according to interim head coach Dan Campbell. Rookie Jay Ajayi has looked very explosive since making his season debut Week 9. Campbell says while Ajayi has a lot of talent, he's not quite there yet. "Ajayi is a young guy," Campbell said. "He's still up-and-coming. He's gotten better, but he still needs a lot of reps and overall from protection to blitz pick-ups, all those different things, to route running. Not that he can't do it, but right now we have a lot of faith in Lamar Miller.
