You know what's good for teams who blitz a lot? Screens to that side. Good thing screens work in GLB
But yea, stuff like this happens every season as it's a problem the AI of dots is so super limited. The only way the AI can adjust is to maybe alter play calls. I mean, in real football the QB usually will do some hard counts, try to read the LBs to figure out where the blitz is coming from etc... Hell, even when i used to play ncaa and madden a bunch i'd do that to figure out if they were in zone or man and try to anticipate where the pressure was coming from.
Maybe a good fix would be something like letting auto-adjust mess with the AI to add a TE to the weakside blocking or other blocking options or whatever is in the AI now for audible to take a look at it. It's possible to slow the blitzes down for sure if you gameplan for them but it's silly that you have to choose between one or the other.
