Just as expected most of the national media is blaming the bad flagrant call as the reason GS lost. I'll say it again, look at the way Green acts when he commits the foul. It wasn't to stop a dunk like Kerr is claiming. Green was mad about several calls (and he had no right to complain about those either). He purposely fouled Zach hard to get the refs attention. He's staring down the ref before he even finishes the foul.
The foul itself might not have been flagrant but as
@dviss1 mentioned in the thread about the Beal travel when you understand people's intentions from watching/playing/reffing thousands of games you can absolutely determine the purpose of the foul and make that judgment. If the Warriors don't like it then tell Draymond to stop yelling at the refs after every call.
