For the first time in a while (despite having good results of late), I decided to look into my opponents in detail. I noticed he passed ALL the time - so rather than sticking to my usual plan, I changed a few Def Plays - my DBs looked better in general than his WRs, so I chose lots of man-marking systems (as has previously been suggested). They scored 44pts :(
I noticed their best players were CBs (which mark WRs). So to counter this I decided to play to my strengths (running plays) which I've noticed thanks to recent stat analysis etc. My rush yardage/completion dropped from usual ~7yds to ~4yds! My passing which I assumed would be now poor increased a bit to ~6yds! We only scored 30pts :(
I know there's lots of ifs/buts and extra factors which could cause these things and without someone analysing the game in great depth, we may never know whether they simply were a better team (we had about similar record in league so far) or whether I screwed up...but is there anything obvious I got wrong in my strategy?
