Not surprising. I knew he gonna to retire after this year. I gonna miss the verbal sonnings he always gave Tennessee. 

Wonder why he decided to do it immediately
Seems rushed and out of the blue. Outside pressures maybe.
I'm not bullshyt but I think he did it today to take the spotlighht off Grier and his Alma Mater. I'm bout 100% that's why. That mafukka a Gator through and through.
