In terms of outside ISO you missunderstood me a bit, i said top teams usualy have top defenders and as long as i virtualy have OD20, OD19 and OD16 with nice IDs and DRs you are almost done.
I agree, but Outside ISO is something between Patient (attack is oriented on 2-3 good players), Base Offense (players take all sort of shots and the ball movement is decent) and Push the Ball (lots of driving if your players have it, passing is important, GE is looking for mismatches); if I have unique players for each of SG, SF and PF position, I think also players you mentioned will have a hard time stopping them. For example, what will you do against such SG:
JS15 JR11
OD20 HA19
DR20 PA12
IS 15 OD10
RB 5 SB 5
I know IS15 on a SG is a lot to ask, but if you focus on IS instead on JS and JR, you can make it. Your SG should have at least 12-15 ID to successfully counter him, or ID10 and SB10...and how many SGs like that exist? (Btw, I'm trying to create a player like this right now - he has only 18y for now though
). A player like this has salary around 160k.
If your SG with great defensive skills should have also great shooting, and a bit of PA, he would have a salary of 210-250k. This is not a small difference in salary. That's why I think the "future" for great teams is to train skills in positions that are not very salary demanding (IS and ID on guards; JR, OD, PA on inside players).
