As for Bigs:
Olynyk and Markkanen likely in that $10M - $12M range which means looking for somewhat more than the mid-level which capped teams can offer. Both interesting, but Markk still has room to develop.
Pre-injured Zach Collins (23) might be had for ~ $5M.
Nice talent. Missed a year with a shoulder injury, then another after ankle surgery. Check on his health. Good news, no knee issues. Could be a real bargain.
ESPN expects only vet min contracts (circa $2M) for the following:
Patrick Patterson 32 - a bit soft but can score and board
Nemanja Bjelica 33 - slow, iffy D, stretch 4, older than I thought
Frank Kaminsky 28 - stretch Big, can bang and board some
Moe Wagner 24 - talented, should be a solid backup C
D.J. Wilson 25 - hasn't developed, but bouncy, long, ankle injuries
Most of these would make more sense if we hadn't drafted ObiT.
Markk, Tank and Mo Wag would be my picks. And real interested in Zach.
