Five teams on mean streaks

Remember when losing Zach Randolph was supposed to condemn the Memphis Grizzlies to two months of muddling in the nether regions of the Western Conference before trying to make a late playoff push once he came back?

Well, they aren't following the script. Unbelievably, the Griz enter Monday's games in first place in the Southwest Division thanks to a six-game winning streak that includes five double-digit wins. Memphis is up to No. 6 in the Power Rankings while posing its record against the league's sixth-most difficult schedule. Believe it or not, only two Western Conference teams have better scoring margins than the Grizzlies' plus-3.7 -- and that's even with Memphis losing its fourth game of the season by 40 to Chicago.
