The end of the Mavs/Nuggets game shows in a nutshell everything that is wrong with the NBA.
A team is upset that they committed an illegal act (fouled) on purpose in an attempt to benefit from it and lost when the official didn't reward them by whistling it and opponent was able to play through the contact and make the winning shot despite it.
The "league" is now even publicly stating the officials missed the foul on the play.
So much for competing with honor and actually trying to play good, legal defense against the opponent. Here's an idea, instead of trying to gain an advantage through an illegal act, make a great play and block the shot.
The guys just don't get it.
