"Why are there still no women coaching men’s sports?"

[LeftyMom]

5. Well, there's hardly any women's football, and women play softball in college.

So I'm not sure just where MLB and NFL coaches would play first before gaining coaching experience. Women's basketball programs tend to be a bit different strategically, but the NBA game is shifting style in a way that would erase some of that difference, so I agree that's where it's likely to happen first, and to some degree has, since the Spurs have a woman in an assistant position and anybody in Pop's coaching tree is likely to get job offers eventually.

The MLB and NFL also have some machismo culture issues that would make them seem likely to be late to the party, especially since players in both leagues are widely regarded to halfass their seasons when they aren't enthused about their coaches.
