Early sub, Nesmith in for Langford. It may not work but I like the move.
This might be a hot take, but I prefer Nesmith on the court over Langford.
I understand that Langford is a very good defender, but he does absolutely nothing else. He has no role whatsoever on offense. Nesmith is probably closer to a neutral defender (though he has improved from the beginning of the season in this regard) but he also rebounds, he hits enough shots to space the floor, and he probably has the best nose for loose balls on this team outside of Smart. I like Langford's potential but I'd rather roll with Nesmith right now.
