I went undefeated last year in my FF league...I had Brady, Moss, and Owens on the same team. I took a pass on the ring from Jostens and pocketed the money instead.
My main $$$ league awards $500 to the League Champion and an additional $100 to the league champion to spend on buying a trophy\ring or either pocketing it. Few years ago when I had the monster combo of Larry Johnson\Shaun Alexander (his MVP 2005 season), I won my league's championship game. I decided to pocket the $100 as I'd rather spend it on something I need\want then just a useless ring/trophy in my opinion.
