To which I have to ask... you were a Play Off Team. How far did you go?
What I'm asking is, could it be the case that you simply were better than him?
The reason I'm asking is this. The recipe shows you CAN have amazing Regular Season Success, but in the Regular Season unless in a brutal Conference or Tough Schedule, you may only see say 6 Play Off Teams.
So I'm trying to find the ceiling. 16-0 in Season is a really high ceiling, but as San Diego's old HC learned, getting to the Play Offs can get you fired if it's a First Round bounce every Season.
Had you not keyed and went all out, do you think you'd still have Won? I mean sure, he'd have done a little better... but if your CBs were simply better than the WRs you already had the advantage, what you did was INCREASE that advantage. Your Pass Rushers were likely better than the Average Pass Rusher he faced during the Season, so he likely faced more Pressure than he had all year against you.
Things like that are what I'm looking at.
By the way, at this point I'd take starting with Regular Season Success at the trade off of a Play Off Team shutting it down... but I like to look beyond as well.
