Having played now multiple seasons of 0.4.3 with different QBs of different talent levels, I say scrap all of it and go back to 0.4.2. Here's why:
1) QB decision making SUCKS! -- Who cares if the QB reads multiple receivers if your 100 INT, 100 FOV QB routinely throws into double, triple, quadruple coverage on every down.
2) You can't control game flow. -- Who cares if the QB reads multiple receivers if you can't use plays to isolate defenders anymore since you don't know WHO THE FIRST READ will be.
3) QBs check down all the time. -- Seriously, watch a game. Multiple receivers open down field? Every QB turns into Alex Smith and checks down to a covered RB.
Basically, it's better to know that the QB is reading one receiver at a time than it is to put up with every random, errant pass. No QB skills matter throughout an entire game because QBs are too unreliable to weight anymore.
