"Don't it always seem to go, that you don't know what you've got 'til it's gone."
Rarely does the modern sports world evoke the lyrics of a folk song written in 1970, but ever since hearing the news of Kerry Coombs' departure from the Ohio State coaching staff for a similar role with Mike Vrabel and the Tennessee Titans, Joni Mitchell's famous words have played on repeat in my head. Now, only Zach Smith remains from Urban Meyer's original Buckeye coaching staff in the fall of 2012.
