The NBA.com website runs a Pick N' Roll contest to see who can pick the playoffs the most accurately. All you have to do is pick the winners of each series and the number of games each series will go. I put together a league for all of us at P&T. Go to the link, and then use this info to join the league.
League name: Posting and Toasting
You'll need to make a NBA.com account if you don't have one - the process should be relatively quick and relatively painless.
Anyway, there are prizes up for grabs, and you get to talk smack to you fellow P&T users. What's not to like? Get in there ASAP.
