Based on the guys in the pool, as far as bigs are concerned, I think Bam is a no brainer, assuming he's not angry about being passed over for Mason for the World Cup in 2019. Myles Turner has the FIBA experience from 2019 and I think he's a good FIBA big man, he increased his 3PA to over 4 per game this year and was at around 34%. I happen to be a big fan of Jarrett Allen so would not mind seeing him as a big. Based on the role he has accepted with the Nets, Blake Griffin would also be an interesting choice
As for additional marquee commits, that's a good question. I think Butler would be great.
