All these college coaches flee to the NFL, one step ahead of NCAA sanctions. Urban Myer, Pete Carroll, and this year Chip Kelley the new coach of the Eagles whose Oregon Ducks were hit with sanctions after he left:
Urban Myer as HC of the Florida Gators signed Cam Newton to a scholarship. Cam Newton was expelled from Florida for multiple drug violations and the last straw was being arrested and charged with buglary, larceny and obstruction of justice.
Myer couldn't get him off once the charges became public. Newton left Florida and accepted a scholarship with LSU where he won a Heisman trophy and a national championship. I'm sure Urban Myer still blames the press for having to expel Cam Newton costing Florida another potential national championship.
