If Tiger Woods has a 10 stroke lead going into the final 4 holes, he doesn't stop trying to make birdie just because it makes the other golfers look bad. People used to accuse Jimmy Johnson of running up the score all the time with both the Cowboys and Hurricanes. As he used to say "It's your job to keep my team from scoring, not mine." If you believe the game is over and you don't want anyone scoring any more points ... fine, you quit trying to score. Stop calling timeouts, quit running the hurry up, take a knee every time your offense gets the ball and let the clock run. If you're in the submission hold, it's your job to tap out and end the match.
You only get a finite amount of offensive snaps in any given game or season, and Belichick, or Jimmy Johnson or anyone else has the right to utilize every one of them. If you've got backups in the game, all the more reason to run your normal offense to evaluate and prepare your backups who usually don't get game reps. This isn't Pop Warner or the family reunion pickup game, this is a multi billion dollar business of highly paid professionals. This whining about "stop making me look bad" is juvenile.
