Might as well make it a gay black woman. Britney Griner?
Realistically, K is going to coach as long as he's in good health. With his grandson on the team, it's likely we'll see him for at least four more years. I'm hopeful that Brad Stevens or Chris Beard would be viable options.
None of the Duke guys have done much of anything. Do we really want to keep it in the family like UNC did with Matt Doherty 20 years ago? Not saying any of our guys are like Doh, but he wasn't proven as a coach. And I'm not sure any of the former Duke players are either. Wojo and Hurley have never won an NCAA Tournament game. Collins has been to 1 NCAA Tournament in 7 years. Capel and Amaker have only been to the second weekend once. We need the best candidate. Period. 99.9% of everyone would be interested in the Duke job. Kevin White would be doing a great disservice if he isn't looking for any external candidates.
And odds are, in four or five years, or whenever K finally does retire, we'll probably have some hot new prospective coaches emerge.
