Remember Rajon Rondo’s Finals ticket giveaway I posted about yesterday? It starts today at 5:00 p.m., and you’ll have to be following Rondo on Twitter to be alerted of the contest.

What Rondo’s doing is dropping basketballs around Boston and alerting fans to their location via Twitter. To get a prize (prizes range from autographed stuff to a pair of Game 4 tickets) you’ve got to be the first one to get to the ball, touch it, and say, “Loose Ball.”

Easy enough, right? So go follow Rondo so you can participate in the damn contest, and remember my only rule:

If you win the Finals tickets, you’ve got to invite me. Hey, I’m the one who told you about the contest, so it’s only fair.

(P.S. – Follow me on Twitter too.)
