If we resign House and Posey, sign Walker and Giddens, that leaves us with 2 roster spots. One of these has to be a legit backup CENTER.
I'm assuming PJ Brown retires, but leaves open the chance of coming back later in the year, just like this season.
This is what I think happens. We platoon Powe and Davis at the backup 5 for the regular season, and sometime around March or so, dust off PJ for another playoff run Lindsey Hunter style.
5 starters --RR, RA, PP, KG, KP
4 rotation --House, Posey, Powe, BB
4 practice --Scal, Pruit, JR, BillW
Which leaves us 2 roster spots will likely be filled by Cassell (now) and PJ (post AllStar break) again next year.
