Jim Harbaugh is refuting reports he has interest in leaving Michigan to return to the NFL.

Harbaugh sent letters to parents of current players and commitments that addresses a potential departure.

Harbaugh writes in the letter that recent reports of him pursuing an exit strategy are "total crap," and that it is "an annual strategy driven by Michigan's enemies to cause disruption to our program and to negatively recruit."

A source close to Michigan said Harbaugh was angry about the reports and that they were "fabricated to hurt in recruiting."

Michigan is 5-2 this season and still has Notre Dame, Michigan State and Ohio State on the schedule.
