Looking at the FA landscape now...
Undersized C? Stromile Swift is still out there as a free agent--he does have a reputation as a shotblocker, is still 29, and misses too many games and lacks the work ethic to really steal minutes from our bigs. I remember some of us wanted him back when he was relevant in Memphis as the athletic shotblocker--well we can now get at the min. Recent years have still shown him to be a serviceable player when given minutes, even if he's lost a step. He can still rebound and block shots as a PF off the bench, and he's more naturally talented than most bench players, even if he'll never reach his full potential. We still need that kind of player, and even if he's 6'9" we can still plug him as an undersized C. BTW, if we want a less baggage, better motor, younger route with this sort of player, Pops Mensah-Bonsu, although still a bit unproven, can do the same sort of work. Shavlik Randolph is also a choice here, but would be third in this set of players, because he's probably an equivalent of Jon Brockman.
Unproven athletic C? Saer Sene may be worth taking a flyer on, but the Knicks and Thunder, two non-contending teams, just dumped him, most likely because he's five years away from being two years away. He's tall and long, and has shown rebounding and pretty good shotblocking in the D-League--stuff we need, again. Better choice than Robert Swift IMO--just not sure about Swift's injuries. Johan Petro's development is rapidly slow, and he's more of a move your feet center than a shotblocker, but he's 22, 7 feet and still has the potential/playoff experience to bank on him as a 2nd string center.
