To respond to the rumor that started this whole thread disaster coming back to life, many people believe that Hart will move us to Nike because his previous schools were Nike schools. But it's not so simple as snapping his fingers and making a change.
1. We are about to begin the third year of a five-year contract extension with Adidas. Any decision is two years away, any change would be three years away, so arguing about it now is rather pointless.
2. Nike's previous contract offers, even when Tennessee was at the height of its football success, have been millions of dollars less than what Adidas has signed us for. Since it's a state contract, Hart can't arbitrarily take a contract that is a million dollars less per year for the school just because he wants to. Any deal, once selected by the UTAD, will have to be approved by several people with the state, as well at UT Purchasing. They actually held up a previous contract extension with Adidas over a fairly minor detail.
3. Our current contract with Adidas pays Tennessee more in cash, coaching salary contributions, and equipment than all but two Nike contracts with schools. I would seriously doubt that Nike would make an offer to make Tennessee one of its top-3 schools financially. Finally, Adidas' current contract with UT (and most other schools) allows them to match any financial offer made by any other company. They have never had to use that clause with a major school.
It would pretty much take an effort by Adidas to drop Tennessee, rather than us drop them, the way the contracts are written. It certainly could happen, plenty could change in three years, but I don't see it happening.
