FWIW, I won the SB this season, going 15-1 and barely winning the title game. The plan is very beatable, and I think most of my ridiculous blowouts were against lesser talent teams that didnt adjust their D plan at all. This plan was setup to be a jerk. 2 point attempts every score, no matter what etc... running only 10% of the time regardless of the score.
Ive tried using the exact same plan on my other team in mfn2, and it failed miserably. I have a much better QB ratings wise and some great WR's but for some reason it didnt click. I think the mfn6 team was more of a perfect storm scenario. Hopefully changes will come soon to prevent the blitz and bomb mentality. But for now, just m2m it, play the pass and blitz.
