If i was to set up a great 5 to play RnG, here´s what it would look like:
PG: In every PG, no matter tactics, I prefer HA,DV and PA atleast 15, this helps Offensive flow. In RnG he needs plentiful JS and JR too. Don´t care much for the rest except stamina(same for all players) who needs to be high (7+). Then as much OD as you can afford, preferbaly around 16. If I need to lower some skills, due to economy, I would choose JR and JS.
SG: JS16+, JR14+, DV17+, HA15+, PA12+. I guess IS(5+ minimun perhaps) is good to have, but not too important in a RnG. FT is also good to have atleast 8+, since this player probably will be fouled alot (taking many shots, high DV). OD as high as you can afford.
SF: My SF of choice would have high OD and ID, around 12+, maybe more on OD(15+, since "everyone" uses a SG on SF-position). High JS (16+) and JR(12+), DV15+, HA13+, PA11+. Then a very important skill in my opinion för a RnG-SF, RB12+. Probably the best player on the team and most expensive to purchase/train. You probably need to lower a few skills but this is "dreamplayer" in my lineup. IS not so important, perhaps 5+ is ok!?
I don´t know how important JS and JR are for the bigmen in RnG, but I´m guessing that they could take advantage of other bigmen with low/non-existing OD and pop mid-range shots with ease... problem is that bigmen don´t get that many attempts per game, regardless of opposition. So I rank the defensive skills higher in my bigmen then JS/JR. But if I have the money I wouldn´t turn down a PF with high JS/JR and a C with high PA. Also I believe they use a lot of their IS when shooting, since they probably are quite near the basket anyway.
PF: High rebounding 15+, As high defensive skills as you can afford, JS12+, JR7+. IS 15+.
C: Very high rebounding. 16+, As high defensive skills as you can afford. Would not "waste" money on JS/JR but maybe on passing. IS 14+.
Minimun requirements for my bigmen would be 7 in HA/DV/PA.
I would like to win rebounding, giving me more possesions.
I would like to have good IS-threat so they don´t use a 3-2-zone without being punished.
This is a rough sketch, not a standard A1-formula so to speak.
