The league

So I took my little one to Nuggets game last night & much to my surprise most of the foul calls were double & sometimes even triple whistles.

Not that we care about the NBA ‘round here, but I just thought that was very interesting.
Have any of you noticed the doubles/triples this pre-season?
Do you all think this could be a new way to call fouls which helps prevent officials from attempting to decide the outcome of games?

I'll tell you what, doubles/triples are very convincing... it's hard to argue calls when the whole crew has it. The only calls that got boos & T's were the solos.
