I don't blame Tee in the slightest. From a strictly professional point of view, it would be viewed as a step down. Why would anyone - from a professional point of view - make a lateral move from USC to Tennessee?
Of course, if he wanted to "come home," that's a different story. But, it seems he didn't. At least not at the expense of his career.
If UT does well these next few years, I could see Mike Bajakian moving on to a HC gig somewhere. Maybe Tee would get a look for that job then. It might turn out even better. Give him a couple of more years to develop recruiting connections in SoCo.
