Simons
for
Okongwu and Kennard
... works on Fanspo Trade Machine. I agree with others that Oknogwu is a PF, not a center, and not a big that could be the lone big. But nothing wrong with getting a good young 6'-10" PF. I would say that he qualifies as a starting level PF. Imagine this rotation:
White
Brown
Tatum
Okongwu
Queta
Pritchard, Hauser, Kennard, Garza, Walsh, Gonzalez,
... is probably a more balanced roster for BOS. I would be OK with that. Not sure if ATL would value Simons enough to do it but we could add second round pick(s). If it took a first, I would probably pass, but I would have a lot of interest in something along these lines.
