In the Post: Matthews has developed this part of his game over the last two seasons. His footspeed isn't great but he's strong for a 2-guard. Getting his back to the basket is a nice alternative scoring path for him. He doesn't use the post much but he can certainly score there when called upon. He reportedly wants to be a bigger part of the offense. Taking advantage of smaller-framed or weaker shooting guards is an obvious avenue to make that happen.
Ballhandling: This is not Matthews' strength. If he's going in a straight line he's fine. Anything sideways is not good news for him.
