I think so...You can't bump a ref even if he actually makes a terrible call. Then other guys, who think they are on the receiving end of a terrible call, will think they can bump the ref...and then other guys may decide to bump and more...so the NBA has to set the tone. Absolutely no contact with the refs...no matter if your Rondo, Kobe or Lebron...no matter how blind the ref is. No matter how bad a call.
No special cases, no special treatment for stars...Automatic suspension.
