"I just want to compete. I'm not expecting anything," Moreno said, per The Palm Beach Post. "I'm coming from a team where anyone can be the starter and it's the same thing with (the) Dolphins."
In other words, this was not an accomplished running back in heavy demand.
Moreno certainly is more trustworthy in pass protection, route running, short yardage and ball security than Miller.
Look for Miller and Moreno to split time as game situations dictate, with Thomas as the odd man out.
Even if Moreno isn't the "starter," his consistent approach will help a backfield that was held under 25 rushing yards on four different occasions last season.
