They stay the same. Sessions is a good player, may improve their perimeter D and can penetrate, but you need the ball to drive to the hoop

As of today, Mike Brown is still their coach, and Co-b will be chucking 20plus shots a game. They are in the elite group, but I doubt these trades have put them over the top to get out of the West.
There are some good teams in the West, and some of them could be more dangerous come playoff time (Dallas, Memphis if Z-Bo can be back healthy, San Antonio). OKC is the favorite, but the rest won't be that easy to beat.
