If Lamar Miller (4.6 yards per carry, five runs of 10 or more yards) gets a hole he can do damage. His speed allows him to get to the second level in a hurry. But if there's any traffic in the hole Miller will struggle. The Dolphins' offensive line is improving in run blocking but Miller will have to do lots of work himself. Baltimore, led by 340-pound tackle Haloti Ngata, is respectable, not great, against the run. The Ravens are tied for 15th in run defense but they only allow 3.5 yards per carry, sixth-fewest. The Dolphins will try to establish the run, but it probably won't result in much.
