It's true, we could use another big, but I think backup 3 is by far our biggest need right now. Perk, KG and Sheed, when healthy, will easily handle the 4/5 minutes just by playing 32 a night each. Scalabrine can kick in 6-10 minutes a night to give those other guys extra rest. Ideally, it's Davis giving 15 or so minutes a night and giving our three frontcourt guys more rest. Also, we may get a 3 that can play a few minutes a night as a smallball 4.
All in all, I just think that's a low priority spot. Backup 3 is of paramount concern. Figuring out Davis comes after that, then a fourth big if needed and maybe a big guard who can handle comes next. But we don't need to start looking for bigs unless/until we make a decision on Davis, and we don't need to do that unless/until someone makes an offer (and nobody has seemed interested in doing that so far) or we pick up a backup 3 and know what our frontcourt needs will be.
