Definitely going to be looking for a backup that can play physical at the 3, and offers the only thing Quisy/TA don't: 3pt shooting.
Prediction: Unfortunately, a Mike Miller buyout is a pipe dream, as the Wiz will be looking to add assets this summer by using him in a sign/trade deal.
Observation: Having this discussion now just reinforces that Danny/Wyc haven't been able to fill the void left by Pose. He was (past tense) a unique player in an important role.
Worse case scenario: Doc ends up using Scal at the 3 to match up with bigger opponents at that position. The bright side is that Doc would actually be paying attention to matchups...
Do you have a prediction of who we could land as a taller backup 3?
No clue. It's always hard to read the buyout market until it happens. Roger Mason would like out of San Antone and would be a nice pickup, but is a SG at 6'5". Will Miami buy out James Jones, the little-used 6-8 shooter? This is probably the level of talent that'd be available: not better than TA, but with a different skill (shooting, size).
Possible to pick up someone else, i.e. taking a flier on comeback guys like Darius Miles, Wally Scissorback, or (gulp) offering some forgiveness to the now-thicker Ricky Buckets? Or giving a D-League guy a shot?
I think someone will get picked up, but probably won't amount to much. Doc will probably just go with Scal at the 3 either way.
