Gawd! Through their first 5, Miami averaged less than 98 rushing yards per game WHILE RUNNING A TRADITIONAL RUN-HEAVY OPTION LOOK. (that works out to about 2.5 yards/rushing attempt, with the caveat that the average includes yards lost due to sacks). How is that even possible?
And before you say that they faced GREAT competition...4 of those first 5 opponents are worse than average against the run (Cincinnati being the exception). The teams they played their first 5 games against (Marshall, Kentucky, Cincinnati, Illinois, CMU) give up, on average, 184.86 rushing yards/game (FBS median = 165.1) and allow their opponents to average 4.48 yards/rushing attempt (FBS median = 4.2).
