Glad I could help, and congrats on your early success!
re: mega assist, ultrapass or the State Farm Concept... from a team building perspective, the best advice I can give you is to draft low turnovers, good defense & solid efg%. Many of these assist monster teams use the 47 defense Boerwinkle as their starter (backing up with the 50-something D Sam Lacey), so a monster center can really apply a lot of pressure. I just lost in the conference finals with a mega assist team to a team that had a shaq rotation. That wasn't the only reason I lost, but it was a big part of it. Most of the time, these teams will be solid everywhere defensively except for center, so I make sure that, if I'm not using a mega pass strat myself, I have a high usage, high efg% center to abuse them with.
As far as coaching strategies against it, that all depends on a ton of factors. This thread has never really been about coaching strats, just building teams & analyzing them to improve your success later on.

Getting over the hump... that's what this thread is all about! Re-read that last section especially over again. Do small tweaks to your squads and see what happens. Pay very close attention to how just swapping one major part of the rotation affects your wins & losses. Examine the top OL teams and see what they're doing to win & apply those same ideas to your squad. You can do it.
