I don't know why you're going ape over Grantham being in the running for the DC position in Philadelphia. Has your defense significantly improved? With all of that talent on the defensive side of the ball, you allowed opponents to score 20+ points in 8 games this year. If it were me, I'd be saying good riddance.
That is because your school stands to be one of the beneficiaries of the multiple defensive recruits that UGA would lose should he decide to leave. You are jaded. Don't make the mistake of being so obtuse that you don't realize that he is even in the running for this job because he IS a good defensive coach. UGA fans most certainly would not be saying "good riddance."
ETA: I am not going "ape" either. We are 2 weeks out from signing day. Not a good idea to lose any coach, regardless of stature, for any school.
