They are good indeed

Even without their two best players from last year (Mensah, Barkate)...

I do believe that Manny Diaz has finally learned how to be a decent HC. While I'll acknowledge that Mike Elko left Duke in a much better state than he found it, Diaz has elevated that program ever since.

Had he cut his teeth at Temple, I think he would have been even better than he is now, but taking that Miami job was nearly a career killing choice, and to be run out of town like that in such a hostile manner must have been painful.
