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.
How can you say that he is underrated? He is already a starting line up of a super team, that already means a lot. And the coach trusts him so much that he is being put in charge to guard star players of the opposing team. Bandwagons may only see the top stars but I am sure real sports fans recognize his talent and dedication.
