Some of the coaches are pretty gnar during games. Running a travel ball program is a career for many of them. $300/mo per kid. If you run multiple teams you could rake in $100/mo profit on each one if you're smart. If your program has a 9U, 10U, 11U, 12U, 13U and 14U team with 12 kids each you can make a decent little living doing it. You attract kids (parents) usually by winning so some of these guys get pretty insane when things aren't going well. Sucks for the kids.
