Prior to this season, I would have said Houston, just because we have always struggled against them, but since Lowry and Martin are no longer there, that's no longer the case. Another team is Denver, illustrated by the loss this season.

After the sour taste of last year's playoffs, it's hard for me to say anybody other than the Clippers, though. I can't think of a team in the league that it would feel better to see the Grizz beat.

In terms of being their most heated rival, I think the answer has to be the Thunder. The first game against them this season nearly turning into a physical altercation wasn't an anomaly. It goes back to that 7-game series in the 2011 playoffs when, despite the absence of Rudy Gay, the Grizzlies gave the Thunder all they could handle in what was definitely a tough, gritty series. The Thunder's big men (Ibaka/Perkins/Collison) don't have any issue with mixing it up in the lane, so they don't back down from the beastly duo of Gasol and Z-Bo when we play them. Add in the physicality that guys like Russell Westbrook and Tony Allen add to it, and it's easy to see how tempers tend to flare when these teams meet. I believe these two teams genuinely dislike each other. You don't see the type of nodding to one another pregame or the jovial conversation during the game that you'll see against other teams. The Clippers aren't far down the list either, though.

I'm going to go with the Spurs for 4 reasons. The Grizz knocked the Spurs out of the playoffs (as an 8th seed) 2 seasons ago so I know that left a bad taste in their mouth. As minor payback, the Spurs swept the season series last year. Recently, Pop rested his best players against the Heat just to get ready for the Grizzlies game. Lastly, they play in the same division.
