First, from what I understand, the beta worlds will cease to exist. That said, I still believe we all need to put as much time as possible into our beta teams so we can/will get true readings. In other words if we put little time or effort into them now and much more when 3.0 goes live we may get totally different results.
As far as your two teams, IMHO talent, or lack of, is the issue, not your coaching. One of the biggest complaints before beta was that talent didn't mean enough for most coaches (I was NOT in that group), so one of the first changes I believe Norbert made was making talent more important. I like the balance now because the way 3.0 is set up coaching/game planning is very important simply because there is so much more we can do, so many more options. I also believe you have to know more about football in general than 2.0 (to win consistently, not to enjoy/play the game).
I think, though, that this is part of the reason the passing game seems so far out of whack. When one coach is either able to spend much more time than another coach, or is simply much better, he can make his opponent look pretty bad in that area. It kind of reminds me of college football in the mid 80's when Houston's Run-N-Shoot would role up HUGE scores, 60-70 points at times. They put up 95 against SMU one yr.!
