Well, I didn't say you can train 4-5 guys, each up to at least 130 skillpoints, and play any tactic you want with them. You just can't. You are limited with time - there's only so much training seasons in a player. You can't train them up to 30 years. Also you can't have a team that can win with any tactic you want. Your team has to be specialized in 2-3 tactics and be effective in executing them. You can't have a team that can play R&G and LI equally good.
I'm training Anžic, who is 201 cm (preferred height for your trainees), for five seasons now and it's not easy. With proper training management, you can train three guys at once, but that would take 7 seasons. After you're done with those three, you spend next 7 seasons training at least two new guys. Then you can play those five together when first three guys are 32...nope, it doesn't work.
So considering time limit, that's the best I could come up with. Yes, those guards are looking like popular LI guards; but those LI guards don't have JS, DR and IS 18 or more which my guys would have. Plus, they would play on SF, PF or C position. Now imagine two of those guards playing SF and PF, a generic SF on center and your two passing bigs on PG and SG. You play Motion. I bet you'd get some really interesting stuff out of your team, like your PG, SG and C passing and driving, and your SF and PF taking jumpers and 3s. Or playing Outside Isolation with same lineup.
Goal of my idea is to bypass the toughest obstacles (namely OD on PG and SG) and to attack the opponent's weaknesses, that's OD on SF, PF and C. Everyone plays LI lately, so their SFs don't have more than 14-15 OD and their PFs don't have more than 10 OD. Their PGs and SGs have OD=20, but with your passing bigs, you really don't care about that, do you? Now take your players and play Motion or R&Gagainst PG and SG with OD=20...
The idea is to "force" game engine to always choose your guards and SF as scorers, whatever position they may play.
