I agree with this article, in regards to Hammon.
http://www.businessinsider.com/becky-hammon-qualified-to-be-nba-head-coach-2018-5If these are things required to be a head coach in the NBA, then Hammon is not ready. But it takes a lot of qualifiers to make this argument.
Hammon did play professional basketball as a point guard and at a high level, but because it was in the WNBA and not the NBA, she does not meet the standards. Hammon has served as a head coach for the Spurs' Summer League team — where she won a championship— and during the preseason, but apparently, that is not deemed "meaningful." And why the magic number of "5 years" for assistant coaching experience? Presumably it is because Hammon has four.
The final point also ignores that Hammon's four years were under Gregg Popovich, arguably the best coach in the NBA, and doesn't consider that four years under Pop might be the equivalent of five or ten years under other head coaches.
The excerpt above is taking a shot at some of the reasons why people have said that Hammon is not qualified, and they are quite silly. Including stating that she played in the WNBA, not the NBA... meaning she is not qualified.
Spoelstra never played in the NBA, he never played professionally at all, and look how he turned out? Many instances of coaches who didn't play professionally and turned out just fine. Christ, Brad Stevens never played in the NBA, and look at him?
I think part of all of this is sexism, and I do feel that the male ego is threatened by possibilities like this. I also think that if she becomes a head coach at some point, some drama will surround it. That is just my opinion. I think as a society we are more open to opportunities like Hammon is getting, but still some close minded/macho men out there that are threatened by such a move. That's just the reality of the situation.
The "Inexperience" argument could have some truth to it in peoples minds, but I am not buying it as the ultimate excuse. Especially considering her background in professional basketball, and her 4 years under coach Pop.
