So I kept hearing about this narrative that Coach Vrabel doesn’t like recruiting. However, I can’t find any definitive article or video of him saying he does t want to recruit. 
But I did find this article written 2 years ago after Day lost to scUM

“Vrabel if that was one of the main reasons he left Ohio State after the 2013 season to become Bill O’Brien’s linebackers coach with the Houston Texans.

The answer I got back, in a nutshell, was that Vrabel actually loved recruiting. He loved building new relationships. He loved talking football with coaches and parents and kids.”

Perhaps Vrabel’s path is similar to Harbaugh. Had success in the NFL, but rubbed owners the wrong way, but then took a job at his Alma mater.
