our league has always been a 10-team league, but this year we've bumped it up to 12 teams. we haven't held our draft yet, but i can already tell you i prefer the 12-team league. it requires more strategy, more preparation & more research (you have to rely more on sleepers in a 12-team league since you're drafting approx 30-32 spots deeper than in a 10-team league). just look at the strategy that's going to have to be used in the 1st round: in a 10 team league, if you have the 9 or 10 pick, you really don't have to think twice about grabbing randy moss in the 1st round (if the top 8 rb's are gone) - because you know you can get the next tier RB on the turn. however, in a 12-team league it's not as simple - do you grab moss w/ the 9th pick and hope 6 straight RB's don't go off the board right after your pick? or do you go w/ a RB and hope another solid RB or Harrison/Holt is available after the turn? i love these kinds of dilemmas!! and of course, 12-team leagues mean more $$$ for the winner!
