Buddy-guy, coming into the league he was considered sub par at every position. NO ONE could have possibly predicted him shutting down Kobe like that, at the start of the season. Let the players play, Im sure you have seen zero minutes of Burks playing in-game, so dont make assumptions off of blog posts, and video highlights.
hayward can play 3 but why make him play 3 while he will have an obvious advantage against his opponents at 2? If he didnt have consistent shooting its ok but he has it so i dont see any reason why he shouldnt play 2.
I dont know anything about burks, i just saw some highlights and he didnt seem to have good defense i hope i am wrong, but i think he will not be worse than brewer overall, only thing is he should have a good personality and work ethic so he wont mess up the team chemistry if he cant find playing time
