In fact, almost all of the best and/or the longest tenured HC in the leage were not players. Having played gives short term credibility in the eyes of dumb owners and dumb players. It lasts a month or two then they either perform or not. Same will be valid for most of the ladies given a HC role just because it looks good in the PR dept. Eventually a few will prove good, probably.
Hammon is a PR stunt and will be even bigger when next year just before the elections she will be on every cover page as the NBA answer to trump machism bla bla bla....
I have no problem with Hardy on the front bench, if the two before him are experienced coaches who actually coached teams, successfully when there were games to win at professional level. Frankly, what can he bring in terms of in-game management, now?
Again, all great if Hammon had ever coached professional basketball players winning games at high rate.
Duncan albeit being the Spurs GOAT, has zero experience of that type.
He will be the first to tell you he needs some time to manage the game from a coach perspective.
So basically we have Pop, and then three guys who never had to call a play out of the pocket with the game on the line. Pretty thin.
