He should get the best type of students-athletes willing to go to Duke plus coach them up when they get there.
He's clearly a solid coach if he has good talent, so I would expect this to result in an improvement over the couple of years. But then they're going to be stuck with a coach that they know is not recruiting at a high level, but they can't fire him b/c he will have been successful for a couple of years (and plus his classes will probably look decent, just not good).
Ultimately, the AD just signed his own pink slip. You can't keep your job as the AD at UT by hiring coaches fired by UM. His one chance is that providing UF cannot simply reload, I guess UT has enough talent that with Cutcliffe's coaching, they should have a legitimate shot at the East next year?
