I would say it depends on how you want to play...you can play small ball or focus on playing in the paint. I try to play balanced.
My lineup is: PG-D. Rose SG-J. Harden SF-P. George PF-K. Love C-M.Gasol Bench Anthony, Westbrook, Irving, Wall, DeRozan, Millsap, Bosh, Ibaka.
I would try to have athletic players at the guards for the fastbreaks e.g. I have 4 athletic guards who can dunk or atleast get easy to the basket.
PG: I would suggest you buy an athletic guard or I would start Curry because you can get alot of easy buckets with him like D. Rose/Westbrook.
SG: James Harden is pretty good because he is athletic and a good Iso-player if your offence stucks at one point. But Kobe is equally good.
SF: Paul George (over Carmelo Anthony) - PG is a better 2-way player than Anthony nearly as good as Melo offensively and a better defender.
PF: it depends on how you want to play - I play with Kevin Love because he can stretch the floor offensively but is a really good rebounder so you can crash the boards/Aldrige plays similar to Love without the 3-pointer but with a better midrange game and post moves.
surely you can play bigger/more athletic - if you wish so I would take Anthony Davis over Blake Griffin.
C: I would take the best rebounder/defender you got: Dwight Howard. You don't need a scorer because you have from PG to PF 4 scorers. He would crash the boards offensively and because he is that athletic you can make the putbacks and you can play alley oops! (Thats my issue with Marc Gasol but I don't have enough coins to get Howard

)
But frankly: you have alot of players - sell a few of them get KD and Lebron James at the 3 and 4 and then you have the best lineup
