I know running up the score when I see it... and that's not it.
My question is how he's scoring once per minute in the fourth quarter when you say you've quit. If you're ready for the game to be over, why aren't you running clock? It's not only incumbent on the winning team to end the game in a reasonable and timely fashion, it goes both ways.
Furthermore, if you want him to run the clock, why are you calling timeouts? That has the exact opposite effect.
Taking knees isn't a requirement until doing so can actually end the game, which means after the 2 minute warning. If Ramesu had the ball then, I assume he did just that, seeing as he didn't score after that point.
I see absolutely nothing wrong in what you described, sorry.
