IMO this is a debate on character and sportsmanship rather than skill or tournament team participation. Superior teams/coaches know before the game begins that they are more dominate than their opponents. Most coaches are smart enough to figure out to stop a press up 25-30 points. After than, coaches are smart enough to figure out to stop transition layups after they are up 40-50. Most coaches are smart enough to figure out to slow the tempo, work the offense for several passes, and work on fundamentals when they are up big. Most coaches are smart enough to put their bench players in early and let them play extended minutes against inferior teams. Most coaches are smart enough to teach class and humility in victory. If there is no way for the inferior team to stop their opponent, than the responsibility is on the winning team/coach to show respect and finish the contest in a classy manner. It's a pretty simple concept. But when you deal with humans traits like ego, pride, and the desire for revenge gets in the way of seeing the larger picture. If a team is good enough to score 100 points, they are good enough to pass the ball around and run out the clock. Just my opinion.
Things that can be done:
MSHSAA change the rule to running clock at halftime if there is a 40 point or more disparity. Teams aren't coming back from that. Game is in hand. Bench players can play, everyone gets home earlier. And the thrashing is over faster.
I am all for playing as hard as possible. If you are up 50+ points at half, changes need to be made.
