This is how my fantasy league involvement usually goes:
I get all psyched up and join one, then devour all available information and rank the players, and execute what I consider to be a "perfect" draft.
The season starts. My team sucks. I start frantically trading, cutting and signing players trying to turn it around,
My team continues to suck. I lose interest and end up finishing 9th out of 12 teams.
So, yeah, I'm totally down for joining! :)
