As an Arizona Alum (but lifelong passionate Illini hoops fan), there are two reasons that I can see giving TL the inclination to leave Tucson. However, they are short term and the bottom line is I think he will rue the day he ever did if it comes to fruition.
1. At the moment, the purse strings have been tightened at U of A due to the 70 million that went missing from the school budget a couple of years ago, not to mention the added scrutiny as a result. I know nothing but this is not nothing.
2. The new AD, Desiree Reed-Francois, may brush him the wrong way. She is far more of a bean-counter than a coach. Again, I know nothing but am familiar with the issues this can provide.
But in the long run, going to Carolina would not be a great move that it might seem at the moment. And yet, to the young, the grass always looks greener...and in Arizona, there isn't much grass and it is not very green most of the year. But the hoops are the same size...as are the basketballs, lanes, courts, etc. And the sun rises bright and crystal clear over the Ricon Mountains almost every day....and those orange blossoms make the place smell like Heaven in March.
