The good news is, Wes Johnson got his "Welcome To The NBA" moment already so it's all uphill from here.
Wes has a lot of work to do, the NBA's a different animal than college. He's going to need to work on a lot of facets of the game, chief among them is being on the same page with his teammates. That applies to the high-post as much as it applies to the low-five.
It'll come with time, Wesley.
