well, to play devil's advocate, a priv8 league can suck if your commissioner is wack.
last season i came form the bottom of the heap to 1st place with a good well rounded performance. i sat on my waiver claim so i could get prior, i had schilling, padilla, odalis perez... miguel tejada and eric chavez. palmeiro. there's only one problem, this one team that was perennially in 1st until i got there was run by the commish's GF. so there were 2 trades to help her out rather blatantly (from the commish to her) so once i got 1st, i believe, one day later there's no inning limit. so this girl basically was out of it with a 4.5 ERA and a 1.45ish whip. so she'd dump her whole starting staff, get 4-6 pitchers who were FA and starting every day, and eventually she soared from middle of the pack to top in wins and Ks, and she holds me out of 1st by like 5-8 points. i was enfuriated since i spent all this time crafting a scrappy team that barely got 1st with a well rounded attack, and then for the last 1/4 of the season this girl just did quantity over quality and out-started me to the league crown (i couldnt dump my staff... when you've got the quality i had, its just not going to happen)
so long story short, i bitched my ass off over that part of the season, the girl said i ruined fantasy baseball for her and everyone ganged up against me. the whole crew (~5 people who are all college friends) wont play with me anymore.. but yeah, i mean, thats the kind of crap you can have if you have a wack comissioner as opposed to a non-existant one.
this season, i'm 3 leagues i'm 4/12, 1/10, and 1/12, and i'm far from looking back at this point. for what it's worth, the 4/12 league is the public league... there's a super-team with basically straight 11s and 12s across the board offensively, and mainly 10s-8s on pitching to hold a 30 point advantage over about 4 of us who rotate in from 2nd-5th place on a day to day basis.
