My head is spinning. Like Richardson but we didn't’ need another wing.
Yes we do. We have no reliable contributors on the wing off the bench heading into next season.
Nesmith is a rook who is still finding his feet in the league who may or may not be ready to play 15-20mpg next season.
Langford is an offensive trainwreck whose inability to provide anything of value on that end of the floor is killing all his good defensive work and shown no capacity to be relied on for anything more than a 3rd stringer to date.
This team desperately needed a veteran wing player who can be depended on for solid minutes. Josh Richardson is that player. He defends, he can handle the ball, he can pass, he can shoot (okay-ish), he can create his own shot. He is a well rounded role player. He is a big improvement for this team's bench.
