I guess it depends on how nice you want to be.
My first ever year playing FF, I drafted some brutal WRs. Just awful. My team was 0-4 and going no where fast. Well, the commish (who was a friend of mine) helped me make a couple of trades that turned my team around and I went 8-1 the rest of way.
Of course the trades helped the commish too. He beat me in the first round of the playoffs and eventaully won the championship. But I was always grateful for his help.
good story and good point.
if you have a weekly basketball game and one friend of yours is always the chump (can't pass, can't dribble, can't shoot) do you keep picking on him, stealing the ball out of his hands, leaving him open so you double-up someone else, etc., or do you play with him during the week, helping him get better and improving the game?
me, i'd choose the latter. help out the dude. not out of obligation, but just out of kindness.
