I can recall in my main money league the commissioner doing something I couldnt believe. We had a league that started at the pizza place i delivered for in college. Back then we just did over all points not head to head.
Randy Moss's rookie season. Very late in the season we discovered that the commissioner had picked up Randy Moss in like week 10 and inserted him in his lineup all they way back in something like week 4 giving him tons of points he didnt get.
I secretly told the other managers and delivery guys before the tackle football game we were having that weekend. They all kept silent till we hit the field. Lets put it this way this former HS bragging football player couldnt make it to work the next day. I can recall 5-6 times where we could have tackled him but yelled "hold him up" so we could lay a shoulder into his gut, legs, etc. to hurt him worse.
Then we told him we knew what he did and we took his commish abilities away, kept his money, and kicked him out of the league.
