Not only would it lack class and be the wrong thing to do in ANY situation, it would be extremely embarrassing for the school if Gruden doesn't come. It would look especially bad if Gruden doesn't even give it a response.
And how would it make the other potential coaches feel knowing they are not the fanbase's first choice? It would hurt UT's ability to hire the next non-Gruden coach. And if Gruden did show interest, our chants would push his asking price up even higher.
