With the offensive line struggling against Central Michigan, Miami shuffled who was playing up front. John Campbell who started the season opener against Florida at right tackle. Campbell played three snaps at left tackle and 20 at right tackle against the Chippewas. Campbell scored a 26.5 blocking grade from Pro Football Focus.

The blocking grades on a scale of 0-100 were all over the place according to Inside the U via Pro Football Focus. In addition to the trouble running the ball against Central Michigan, the Miami offensive line allowed four sacks.
Diaz, offensive line coach Butch Barry and offensive coordinator Dan Enos need to figure out the offensive line quickly. Miami’s two most critical games this season to contend for the ACC Coastal Divison title are the next two weeks.
Virginia Tech next Saturday and Virginia October 11. Both of those games are at Hard Rock Stadium. The porous Miami offensive line will face a Virginia Tech defense 36th in FBS in sacks and Virginia who is tied for first.
Finding the combination that works upfront is critical. It could be difficult with some of the Miami offensive linemen good as pass blocking and others are better against the run. Getting a quintet to work together well and consistently will be crucial to the success of the Miami offense for the rest of the season.
