The Midwest Division is just a bit too strong now, with the Grizzlies and Nuggets getting into the mix. The worst team is the Spurs and they not even terrible.
Grizzlies might take the divison lead only 1 game back of Houston, Denver, and Dallas and might extend there streak to 7 with 2 easy games coming up vs. Miami and Atlanta, and maybe even 8 or 9 if they beat the Nets or Spurs. If they win 10 in a row ( 10th game is vs. Kings) then we will all know they are for real this year.

Many teams tend to have a fast start then go down the drain over the 2nd half of the season ( look at the pacers last year)
