I think Poetl is great value anywhere outside the lottery. I see him as a rich man's Steven Adams (who isn't a bad player himself). He's better offensively at the same age, and has elite defensive potential if he can add another 10-20 pounds. I wouldn't be surprised if he gave us 12-15 points, 7-9 rebounds, and ~2 blocks within a couple of years with no major weaknesses.
Realistic chance that he's a better pro than Turner, Looney and Kaminsky and possibly challenges for the 3rd best center in this draft after Towns and Okafor.
