Geez, they didn't choose Bender over Chriss. They got rid of Chriss because he was predicted to be a bad fit with Ayton. Theoretically, Bender should be a much better fit with Ayton than Chriss. I don't think any of the Suns front office are lamenting they got rid of Chriss and not Bender.
Since at this point it looks like we're destined to tank again, let's look forward to Zion Williamson at power forward (hopefully selected by a different GM).
