I, too, missed out on the fantasy league, so I set up a Fantasy Keeper League, which could be kind of fun if we kept it going.
Anyway, it's on NBA.com's fantasy system, so go here:
League Name: BullsLeague
Hopefully enough people sign up to make it a really good season. I assume all the rules are listed on the fantasy league's website, so I won't waste space going into them here.
