Ugh ... didn't catch this last night, but just read it in Feschuk's article this morning. This isn't good by any means. Coaches vs. players is never a good thing especially when the player is "snapping" back.

The coaches harp, but is anyone listening? Marc Iavaroni, the assistant who specializes in defence, was seen chewing out reserve guard Marco Belinelli during last night's third quarter. Belinelli's response? He snapped back at Iavaroni, then moved down the bench a few seats so he was out of shouting range.
