IT is probably the main culprit, actually. I recall him turning the ball over (1/5) and not even attempting to get back on D to stop the layup; worse, someone else did (can't remember who) and nearly contested the shot. We all know that's mighty bad, esp for a guy like CBS.
That, the ill-advised shots, jawing with Teague, and whatever happened in recent practices may have brought things to a head. Then a lot of other guys may have checked out due to frustration or lack of involvement (e.g., Amir, Sully, Jae) and others played like crap b/c they seem to be a product of their environment (e.g., Jerebko, KO, again Jae).
Turner also put up some ill-advised shots and couldn't be counted on to pick up where IT left off tonight, unlike last game. This would also make more sense of Lee seeing 25 minutes tonight (7, 17, 15, 5 mpg in the last 4).
So one guy brought it tonight on both ends. What's the solution? Stevens doesn't seem reactive enough to drastically change the starting lineup, unless he's just proving a point (still unlikely, but possible). Is it time to start to consolidate the roster? Or weather the storm, and wait patiently, for our first-choice trade targets?
