Good teams do lose to bad teams - that's a fact. The way you loose sometimes is more important than who you lose too. Sometimes, the shots just don't fall. Or you can't buy a FT. Or you run into a team that can't miss no matter what you throw at them. And sometimes you just play like crap.
What is maddening is the poor execution and lack of energy - Turnovers, shot clock violations, and overall confusion especially late in games. Way too many wasted possessions, and low percentage shots being heaved to beat the shot clock by guys who should never have the ball in their hands with less than 5 seconds on the shot clock unless they are in shooting position (I think I've heard enough of Mike Barrett saying "Blake with the ball up top, 5 seconds on the clock, better hurry." Errnntttt. "Another shot clock violation")
