How would the old school NBA players feel about this being a foul call

Giannis Antetokounmpo blows the putback dunk and the ref explain to Jalen Brunson why she didn't call a foul at the other end - Brunson gives her the thumbs up

Westbrook failed to draw foul &amp quit on the play complaining to ref. His man was left to fastbreak for an easy bucket.
