John Salley vehemently disagrees with the NBA's decision to hit Draymond Green with an indefinite ban this month ... telling TMZ Sports the suspension was a complete overreaction.
The four-time NBA champion said this week he's in favor of sidelining Green for smacking Jusuf Nurkic during the Warriors vs. Suns game on Dec. 12 ... but he thinks the indefinite part of the punishment is simply taking things too far.
"You can have a conversation, give him a certain amount of games for him to simmer down and have intelligent conversations with him," Salley said of Green.
