Doc is preparing for Miami. The entire team has their mind on Miami in fact. How do we match up with them? Play small ball
Matching up with Miami by going small probably isn't going to work. Using size to score on them, and then figuring out how to match up with them at the other end and not getting that size exploited might work, however.
That's why I like Sully as an answer, assuming he will be ready to play at a high level this season. He's big enough to get work done inside, but should be nimble enough to guard guys on the perimeter. he also can become a bit of a banger, providing some paint muscle that the Cs didn't have last season.
