I don't consider the state of the game quite this bad... but I've been saying since at least M11/12 that the AI either needs to be tightened or further segmented or something to allow for a difficulty that falls somewhere between All-Pro and All-Madden. Seems like the majority of the traffic on the slider forums is going for precisely that goal.
While a lot of the issues are at the very core of the game design and are never truly going to be fixed until that core is rebuilt from the ground up... There are glimmers of hope... When the CPU has smart play calling, a lot of the other warts become easier to live with. I've played a handful of games in my current All-Pro based CFM where the CPU calls a great game, mixes up play calls, etc. Problem is that those are too few and far between.
