From Kelly Dwyer in Sunday's SI.com: Dwyer is one of the sharper mainstream NBA writers, and I must reluctantly agree. Sure, we had several starters feeling their way along after illness or injury. Sure, it's smart to save something for yet another two-month stretch of playoff games. But even this team's biggest fans worry about that little switch. You know, the nonexistent switch our guys say they don't turn on and off ... even when it's pretty clear they do. I'm not a sky is falling, trade 'em all kind of guy, but I find myself hoping that Joe has a shake-up in mind after this year's title chase. What do you think? And how much change is enough to bring back the fire of four years ago?
