The Warriors appear to be going against recent NBA trends with their trade for Jimmy Butler. ESPN's Brian Windhorst explained Friday on "SportsCenter" why the Butler trade was a move in the opposite direction of most NBA teams in terms of roster construction. "Well, it's interesting because if you look at the top teams in the league, the [Cleveland] Cavaliers, the [Boston] Celtics, the [Memphis] Grizzles and the [Oklahoma City] Thunder, they're all very young teams," Windhorst said. The Thunder are the youngest team in the league and they're very deep.
