The highest number of teams I compete with is 12. About 8 of the leagues are pretty competitive, the others are real lax....I just go on there to change the pitching 2-3 times a week. And to add a couple players here and there.CDCollect said:Haha 18 C'mon there is no way you can keep up with all of that. A Fantasy Baseball Team if playing in a competitive league can get very tedious. Dropping and Adding players, checking match-ups and there is alot more. I can see having a few teams but 18?! It's not much fun if your playing in a league with people that have 20 other teams because its not as competitive.
