i used to do 2 or 3 a year, but this year im going to do one. i was apart of the gif. last first two keeper leagues on year i didnt do any at all
I typically average about 3 per year. Its hard for me to keep track of all my players at each spot when I'm watching games on Sunday. If I do more than 4 leagues in a season, then I end up rooting for and against myself.
I played in six last year- CBS Sportsline, 2 NFL, Yahoo, Fox, and ESPN. I think I won two titles out of all of those- and the ESPN I lost once during the regular season and imploded in the championship weeks so I finished 2nd. I felt like the Colts (up until last season, of course).
I joined a Yahoo.com one, and I have 3 on NFL.com. I joined other people's but my own one still has 3 openings. I thought I would have enough people to fill it, but I changed jobs recently and lost touch with someo of the people that were in it last year, if you want to join, the details are at the link below. http://gridironfans.com/forums/showthread.php?t=34574
