In general, I don't like networks featuring active players as analysts. I always take their critique of other players with a grain of salt because they are all competing for the same roster spots. They can hate on a team all they want, but remember: the reason that an active player is working as a play off analyst is because their team lost and the team they are critiquing did not.
But yes, Draymond is a dirty player. I do think he is not Andrew Bynum (who actively injured other players) but more out of control than Metta World Peace.
