One of the more interesting games on the schedule for Michigan this year is Air Force. Not just because it will be Michigan's season opener, but also because it's the first time Michigan has played a service academy in years and Air Force brings in a team with varying expectations. Coach Troy Calhoun has built a respectable program at Air Force, but with key offseason losses, there are some serious questions about whether he can field a team good enough to continue its recent program success.For Air Force, things always start with their blistering run offense. The team amassed over 4000 yards on the ground last season and had three rushers that had at least 500 yards, including leading rush Asher Clark with 1110 yards. Despite this, there are still some concerns for Air Force's offensive potential. The Falcons will be returning Mike DeWitt (2nd leading rusher), Wes Cobb (4th leading rusher), and Conner Dietz (5th leading rusher), but are losing two of their top three rushers in Asher Clark and Tim Jefferson, Jr.
