Obviously, we can't hear what the coaches are saying to the officals during TV games but I can't imagine that they're yelling about how great the calls are! 🙂
Also, there were several situations, on both ends of the floor, where subs and coaches were jumping off the bench when they didn't like a call, when they were signaling violations, or they were waving towels at the officials.
Crap like that trickles down to high school.
