Its no easy answer to this. I think what your saying is very debate-able. I might have one of the best outside shooting in all div 4 .Go look at my salary those guys are not weak in skills. The other team just play LI /m2m and boost od, boom the "W" is there.
Should i spend 250K$ a week on my team or should push it 400K a week which is the max I can afford before I break my bank account and is run off bb for ever. You make it sound like these super upper league teams have it figured out in reality a few of my personal players come from those same upper teams your talking about skill about the same.
While I have not played in B3 or anything of that nature. I assume the best teams that are beating li have a 25 million dollar team or has spent as much. Maybe even renting those player for a season or just for the b3 tourney.
Li is over powered along with od in some cases, because a od with od 9-13 should not be stopping jr15, js16 which I do have. So I don't see any easy answer , waiting for data and results don't make this any better. I don't have all the answers but what I do have is a lost to teams that play LI and high OD, in lower division.. Let me tell you my salary is high because I have outside shooters not LI players.. My team cant play LI or low post to save it life.
The only applicable analogy here that I can think of is that not everyone graduates in the top half of their class; there also have to be everyone else that makes the top half possible.
Salaries are pretty meaningless, especially in IV - I got far better production out of 10-15k salary guys in my time there than many teams got out of 30-40k players. But I refused to buy big men unless they had good handling, passing and OD - and as it turned out, that worked quite well. I'm taking that further by training my own big men with even better guard skills, and having seen that succeed as well as it has to this point, I'm probably going to finetune this with another generation of guys in a few seasons.
Hopefully some of this will help you make progress. Don't buy players with bad OD, HA or PA, ever (unless you're going to train them and fix that). Try not to end up with a player that fouls as frequently as your C does. Or, you know, do whatever you want to do and keep making that top half possible.
