In this trade Phoenix gets younger and some more depth behind Marquese Chriss, and the Nuggets get their point guard. Lets face it in the West you need a star point guard to compete. You have to play Westbrook, Chris Paul, and Stephen Curry to name a few. The Nuggets needs someone who can defend these players frequently.
Eric Bledsoe, who has been rightfully named Mini-LeBron brings a lot to the Nuggets and while playing next Jokic he can focus on scoring the ball and playing defense while bringing some veteran leadership to the Nuggets.
Adding Eric Bledsoe would almost guarantee a Top 5 seed in the West.
