IMO, it's not really about size - it's about spacing.
I think that the Jazz can definitely get away with a lineup of. . .
Favors/Gobert, Hayward/Lyles, Hood, DeRozan/Burks and Exum/Hill. Don't ever want Lyles at center. Favors can do that job in small lineups just fine. Defend to the edge AND bully people inside with shooters outside giving him space.
DeRozan and spacing don't belong in the same nation let alone on the same team. With Hill, Hayward and Hood we have several good outside shooters. Hopefully Burks and Exum are adequate. So why screw that up with DeRozan. Let some else over pay for him.
