Sure, she can coach, and may do a great job of it. The big difference is the quality of play. That’s why the NBA has the crowds and the WNBA has the empty seats.

Took my two young nieces to see an ABL (precursor to the WNBA) game in '97 - was disgusted and embarrassed (for my nieces) to see girl couples making out in the stands.
What the hell is wrong with them? I mean, you don't normally see heterosexual couples making out at pro sports games, even real drunk ones hardly ever do that.
