Schlafke was a four-time team Most Valuable Player award winner, three-year team captain and led the Bulldogs to a 33-14 record while not missing a start in his four-year career.

SIU averaged 219 yards rushing that season, the third-best average in the nation.

Former Coyote defensive coordinator Chuck Morrell hired Schlafke to be his offensive coordinator and quarterbacks coach at Montana Tech in 2011. In year two under Schlafke and Morrell, the Orediggers improved to 8-3, won a conference championship and secured an NAIA playoff berth.

Schlafke joined Western Illinois’ staff when Nielson became head coach there in 2013 and immediately the move paid dividends. The Leathernecks, which ranked last nationally in total offense and next-to-last in scoring in 2012, jumped nearly 30 spots among the national leaders in rushing, passing and total offense in Schlafke’s first season. In year three, Western Illinois returned to the FCS playoffs for the first time since 2010 and advanced to the second round to culminate a seven-win season.
