I dont think he has a good reputation.. but i also think its overblown, and no, I dont think leading the league in technically is the same as being a habitual tripper (Allen) or a habitually dick-puncher (Draymond).
Honestly, I find Cousins to be closer to a Bill Lambier than either of those two. Now, a little more unstable than Bill, but a no-nonsense, play hard in the paint, if they refs dont see it- type of player.
