Sacks (realistically) do get counted against total offensive and passing yards, but not against individual passing yards, so that might be part of the problem.
The point of Madden for me (and many other similar players) is to play an offline single player franchise. For the first 13 weeks or so when the game was out, when the player could easily sack the AI 5-10 times per game calling mostly base defenses, and the QB would never scramble, basically handicapping the AI offense and creating wildly inaccurate stats, yes that is broken.
Similarly, when if every time the human kicks off the AI ends up at ~15 yd line (which has been the effect so far), and most AI players can be caught from behind in the open field because they slow down for no reason, similarly handicapping the AI offense and creating unrealistic stats, then yes that is broken as well.
This is not nitpicking. It is no fun to wrack up stats and win games when you know the AI teams are not really "trying." For the game to be considered functioning, it has to have a competent AI opponent, and the ability to produce generally believable results and stats from plausible strategies and play calling.
It seems to effect players with any trait besides "Never."
Anyway, on most rosters, the vast majority of offensive skill players have the "brace all" trait.
