Couple major issues here in my opinion.....
Need more bench. Paul Miller is supposed to be our scorer. He shouldn't be our PG. He's a much better off the ball scorer. The lack of depth is wearing him out, and not only he is not able to hit shots at the end of close games, but you're asking him to handle the ball, which not only takles away his offense, but his tired legs are possibly contributing to turnovers.
Also, Jacobson's 3pt % is down considerably from last year. Looks like he is working through a little slump in that area.
IMHO this will be a challenge for Richman to work out and I will be anxious to see what he does about this. Need to find another ballhandler somewhere. Need to figure out what you want from Miller. Do you need him to score or do you need him to handle the ball? You're not doing him any favors by asking him to do both. He isn't an on the ball scorer.
