Of course, I've got to go with the Mavs on this one.
This is the most crucial game of the series. If the Mavs win, then they've got the momentum in the series. If they lose, then this series is over. They've only lost five at home, and this is a must-win game. Let's keep it going.
BTW, I read something interesting on ESPN's Page 2 - is Marquis Daniels playing Steve Nash out of his job? Personally, it's hard to imagine the Mavs without any of the Big Three, but if Daniels could take over at the point, possibly Dallas could do a sign and trade to acquire a real post player.
