no problem. it does get confusing because there are so many ways that people play. i had no idea that people would enjoy watching an cpu vs. cpu game. well, people do and tweaks need to be done to make that playable to them. there are people that think people like me that play 99% of their games controlling one team against the cpu are crazy. they think, 'it's so boring to play against the cpu all the time!' so their tweaks need to take into account human vs. human play.
so you'll see a slider set or a suggestion on tweaking attributes, try the changes out and wonder what the heck the person was thinking. then you'll realize that the tested at cpu vs. cpu or human vs. human...doh!
i've been playing my last few games on a 'crib multiplier' of 1.62 which puts my settings more or less right in the middle of all-pro and legend. i've also set the interception slider to zero. i have had some really bad games by the cpu qb and some really good ones and you wouldn't guess who had what game by the names (harrington ripped me up a couple nites back, i totally shut down trent green AND priest holmes last nite for example). i haven't felt that interceptions or overall db ai has been a problem but i understand the complaints some have.
