I tweeted this info earlier today:
Unimpressed by Utah's 10-game streak because most of their opponents are -.500?
#TakeNote of this list of losses to sub-500 teams by the NBA's best teams over the past 10 games:
LAC 1 (MEM)
MIL 1 (SAS)
BOS 2 (SAS/WAS)
TOR 2 (SAS/POR)
DEN 3 (NOP/WAS/CLE)
HOU 3 (GSW/NOP/MEM)
MIA 4 (WAS/ORL/BKN/NYK)
*LAL have not lost to a -.500 team this season
Note also that Utah has played four of the teams that have beaten a top NBA team over their past ten games. Four out of ten of Utah's recent opponents recently beat a +.500 team. (ORL/NOP/WAS/BKN)
Of course, this doesn't account for any back to backs, home vs. road, etc. But I still think it's telling. Also, dang the Lakers are doing well.
