This was one of the more surprising trades of the NBA season. Kendrick Perkins is a proven winner, and his injury was the reason why the Boston Celtics choked in game 7 of the NBA Finals last year. This is a move to make the Thunder more physical, but the Celtics are a team living in the present. Boston's window of opportunity is two or three years. With Kevin Durant being a juggernaut of a player, this makes the Thunder a more formidable team in the Western Conference.
