Sexist coach?

Maybe not didn't care maybe just is better with women? I've known many coaches that are just better at relating and coaching one gender over the other.

It could be a lot of things, other than sexism...

Most likely (given the women's DII national level of success) the women's team has a good complement of scholarships. For Title IX reasons the men's program may have very few or no scholarships at all. The men's team may even have some roster restrictions, while the coaches are encouraged to bring on as many women as they can. As a result women's recruiting is at a much higher level, and though they won't admit it, the coaching staff is probably more invested overall in the women's team simply because they are better and people like to win.

I think Joe Bosshard is the sexiest coach.

I can almost guarantee you that it is completely tied to scholarship dollars. Would need more info on the make-up of the Athletic Dept. But at D1 and D2 with football then women's track / xc is funded at a very high / max level.
