NBA power rankings 2012: Heat fall to sixth in latest SB Nation rankings

Despite a 5-2 record and a 3-1 week last week, the Miami Heat dropped to sixth in the latest SB Nation power rankings.

Grizzlies take down Heat 104-86

The Miami Heat fell to the Memphis Grizzlies 104-86 Sunday night, putting an end to their four game winning streak.

Chris Bosh had 22 points and eight rebounds to lead the Heat while LeBron James scored 20 points, pulled down 10 rebounds and dished out six assists. Dwyane Wade was off all night, scoring just eight points on three-of-15 shooting.

Wayne Ellington surprisingly led the Grizzlies off the bench, pouring in 25 points on an incredibly efficient eight-of-13 shooting. Rudy Gay had 21 points while Zach Randolph added 18 points and 12 rebounds. Mike Conley, Jr. also scored 18 points and dished out nine assists for the Grizzlies.

Defense has been an issue for the Heat throughout the young season and that was the case again Sunday. The Grizzlies posted an effective field goal percentage of 52.3%, going 14-of-24 (58.3%) from beyond the arc. Ellington was seven-of-11 from three-point range himself.

After Sunday's game, the Heat are now just 24th in defensive efficiency.

The Heat will be right back in action Monday when they take on the Houston Rockets, the third game of their six game road trip.
