Porzingis is identical to Andrea Bargnani, but with more health issues. He's a national name, because he plays on the Knicks and is the "great white hope". This is the same idiot machine that created "Linsanity".
We already gave up the next James Harden to trade down to #3 where our options are the next Pippen/TMac or the next Paul Pierce. You don't trade that for Andrea Bargnani 2.0.
Tyler Zeller is a better defender and rebounder than Porzingis. If Tyler Zeller could develop an average 3 point shot and was given 33 minutes per night on the worst team in the league, he'd be a better version of Porzingis. Porzingis would not even start on a good team. He will never be an allstar.
