It is never good to lose. I never pull for the Vols to lose. If UT is 6-6 and the powers that be believe they can get the right guy then Dooley is gone. If they don't feel they can upgrade then it gets more complicated.
And before ignorant posters jump on this post and say "It can't get any worse"... it can. Hiring an equally bad coach would be "worse" because you'd have another 3 years in purgatory while he got his chance. Hiring a somewhat better coach is also worse. You only change if you KNOW you have a guy who can raise the program. Otherwise, suffer another year and try to find that guy next fall.
This isn't the gratification most here want... especially those who are personally offended that Dooley coach poorly and so find it necessary to attack him in hateful ways rather than just dealing objectively with his failures as a coach. But the truth is that the wrong move can have longer, more damaging consequences than keeping Dooley while looking for the right guy.
This is the nature of the coaching carousel. Notre Dame took a spin. Davie, Willingham, and Weis all looked like great hires... Willingham and Weis were considered definite upgrades. They hired and fired 3 guys after Holtz... and while he's having a good year this year... Kelly isn't out of the woods there yet. USC went through an extended period of frustration before Carroll arrived. Texas had a long drought. Nebraska had a long drought. Miami has been down for years while trying different coaches.
No matter how optimistic you are that one guy or another is the answer... there's NO guarantee that he is. Dooley needs to be fired. He has not proven he can coach on gameday well enough to compete in the SEC much less win championships. But UT needs to hire the right guy or the process just repeats itself...
