Draymond is the most underrated player on the Warriors since all the attention goes to Durant, Curry, and Thompson. Guy is a spectacular all around player and does every little thing to help his team win even though it doesn't all show up on the stat sheet.
Disagree. He was already being recognized for his great defense since then. He is known to shut down big names including LeBron James especially during their 4 consecutive finals meetup with the Cavaliers. Also just for reference, Game 1 in the on-going 2019 NBA finals, he posted triple-double. Game 2, an almost.
Maybe it looks like he was underrated to you because he is not a scoring machine unlike those 3.
Green's role is definitely different to Durant, Curry and Thompson.
