I won't be using the most expensive versions of any of my first 3 picks. Just not enough salary. My original thought was to use 29DReb Mutombo and 90D Moses and try to own the boards. The sacrifice in defense is worth the money savings. Oscar doesn't really fit with this team, but he adds another rebounder at the point. Also, I thought Steph or Mookie would fall to me in the 3rd, so I had to redirect.
As for shooting, between Barry, Oscar, and Prince I have over 350 3PM and solid (not great) perimeter defense. The issue for me is finding a way to fill the bench with guys I can trust. Guys I thought would last (Batum, Kawhi, Horry, Posey) are gone so I am trying to think of backups who won't kill me on the wings. Plus, I may have to switch back to monster Moses since I can't find a backup PF who doesn't make a mess of things. I was looking at Henson for awhile and even that fell through.
I went with Johnson because he fits the usage/D model set by prince and I basically have the same guy at SF all game long. I took Charlie V, because I'm still trying to figure out the bench situation, and he has a range of salaries that I though would be easy to squeeze in. AKA if I don't want him, I'll use his 300k season.
