I am loathe to use the word classy in any context. I think of it largely as a cudgel used by any of many people to codify behavior they find agreeable (and assail that which they find objectionable) by their own particular and often shifting standards. There's no one barometer for "class," and thus "classy" is as worthless a word — especially in discussing sports — as any in English.
Jeremy Foley's retirement press conference is going to be called "classy" a lot.
I don't think it was that. I think it was honest, straightforward, dignified, and respectful, both of the job he's held and the work he's done, and I think it gives Florida fans one more reason to be very proud of the person who has led the Gators from, as Foley notes, "sleeping giant" to colossus astride the world of college athletics.
