Good analysis of APB's Madden D. I never played Madden, but since it's just regular people playing mostly, I suspect they pass at a higher rate than the real NFL - hence the reason for APB's Madden success. I suspect he also benefits from having Jaire, Stokes, and Savage healthy and playing the way they are supposed to play in the Madden game.
In the real world, though, it's even more iffy having ILBs who can't cover guarding the short middle zone or worse yet, manning up with a WR or even a quality TE.
Assuming you're correct about LaFleur demanding Barry play that semi-Fangio scheme, it appears we're sort of stuck with the same thing even if we get a new guy. The even bigger problem with Barry, though, is his apparent inability to adjust. Hopefully we get somebody better that way.
