I think I can sum this up.
Freeze allegedly committed acts of questionable moral character. With the exception of any questionable actions in the Oher recruitment (which Fulmer still has his feelings hurt over, apparently) none of them were directed at UT or meant to insult UT.
Jones committed no acts of questionable moral character of which I am aware. What he did was take a job at a rival (perfectly fine), travel back to Knoxville (perfectly fine), then proceed to make sure his celebration of a win over his former program were well publicized (a definite slap). In this case, he should have followed the example of Lane Kiffin (not a phrase used often.) Kiffin came here, coached, acted with dignity, then left. No cigar shots or celebration pics were posted.
People will forgive a moral straying. They will even forgive a direct action taken against them. What they won't forgive is a slight, a petty insult. Robert DeNiro says it best in Hoffa:
"If a guy's close to you, you can't slight 'im. You can't slight that guy. A real grievance can be resolved; differences can be resolved. But an imaginary hurt, a slight - that mother****** gonna hate you 'til the day he dies."
