Well, my main problem is that anyone sees his roster knows hes not going to be any better next year.
His only possible keepers are: (10 team league, keep 8)
Now, for a 10 team league those arent exactly the best bunch to pick 8 keepers from. Obviously, manny and vlad are studs but hte problem is aside from them he doesnt have much to choose from. I try to advise him, hey trade Manny for 2 good keepers, but not as good as him, so you can spread out your talent. I mean, to each his own but its like he makes no effort to improve his squad.
Then he will post something like:
Schmidt and Contreras are both available in a trade for a top 80 player, no OFs
He gets offered Giambi for one of them, who is ranked in the 40s and rejects.
Basically, when someone offers him a bad trade he posts on the board a 5 paragraph message saying why its a horrible offer, and that gets old. His last post really crossed the line but I dont enjoy locking people out and being a Commisioner/Hitler, I just delete the post and tell him to watch it in the future.
However, for me, Activity is most important but also the social atmosphere, as this is a non-money league and almost all friends. When one person rubs multiple people the wrong way, he might as well go if he isnt especially skilled anyway.
