It isn't Miller or Al's fault most of the time. Miller has been horrible defensively because most of the time he is playing 2. If Karl takes that away we should be fine. Having the same team will be great to see the development and chemistry really grow. You could always get a back up pg anytime. Now Mcgee can come off the bench still (if that happens) with Miller!
Maybe the best thing to do is nothing. Let Rudy go and play jham. Re-sign both TY and Mcgee. Pick a pf who can shoot and has defensive upside in the draft. Pg's come more than bigs so I think we should draft a big who can score when Al leaves.
