Just booted the colluding guy from our league. I had settled on letting it slide because it ultimately didn't affect anything, but then he went and opened his mouth.
I sent out an end-of-season wrap-up message today in which I noted some changes for next season. I mentioned that teams who obviously collude with each other would be subject to having their rosters locked and be ejected from the league. The moron said he had a big problem with that rule because if he wants to sit players to set up a better playoff scenario for himself, it's his right. He also called me "****in' bush league" because for the past two seasons, rather than playing a third-place consolation game, third-place money has gone to the semifinal loser with the most points on the season, as sort of a bonus for 22 weeks of performance. This season, it happened that I got the third-place money and he didn't.
I told him it's bush league to tell another owner who you are playing against that you want them to have a bye so you're going to intentionally lose the week, and since he would obviously do it again given the circumstances, he's gone.
Guy caused 90 percent of the headaches I have in this league. Good riddance.
