I would have agreed with you just a few days ago, but with how bad he's played this series really if Draymond doesn't come down to a "reasonable" price he may be gone when is contract expires.
Meyers did trade Igoudala in order to make the KD sign and trade.
Again, I think they keep Dray around to keep Curry happy, but Draymond will definitely need to be reasonable with his salary and eventual role.
I've really soured on Draymond since the year Curry broke his wrist. Draymond claims to be a leader, but instead of being a true leader he played like ### and got thrown out of games to get the night off since the team wasn't playing "meaningful games". Great leadership there. That year actually made me respect pre-Lakers Russell Westbrook and Chris Paul more because they bring intensity every night.
I always gave Dray the benefit of doubt since then, that he'd step it up when the games mattered, but this finals really just solidifies that he's completely lost faith in his ability to shoot the 3 and make free throws. This leads to telegraphed passes and DHOs. Usually every team has someone that the Warriors offense could pick on, but the Celtics defense is too good.
Honestly, Draymond is annoying to me as a Warriors fan, so I definitely understand all the hate he gets.
