For all the talk about them revolutionising small ball lineups, at the end of the day there not big enough to beat another great team with bigger more athletic player's .
Adams, Obama, Durant, Roberson, Westbrook just too big and talented for them.
Also have done well with Adams, Kanter, Durant frontcourt. OKC does have two of the five best players in the world and that sure helps, but deep down I could not wrap my head around having a 6'6" PF in green as your 2nd biggest player.
