I think it's a combination of things. Some type of replay/challenge needs to be implemented. The Refs need to be held accountable I agree, but why isn't this something addressed when the Player's Union negotiate?
These players who whine almost all the time or whom the refs feel intimidate them, need to adjust their on court demeanors, at least until the 2nd half of the season haha..this is where more veteran players need to be on each team, teaching these guys how to be professionals. I like that Hayward workman, a former NBA player, is a ref. Having for ref that were former players, as well as checking THEIR demeanors as well would help.
In a loosely related subject, that white female ref could get it..
