I'm all for making a realistic game, but the more attributes are used to determine the outcome, the less cause and effect there will be. That's a big issue with 2.0, nobody knows what's really important so nobody knows how to recruit towards it or exploit it.
Now, if you expand the PBP, go for it. But let us know if our OL was beat by a bull rush, a great swim technique, speed off the corner or a more athletic DL who he couldn't block. Same with our RB, did he outrun someone, plough through a tackler, make an athletic move the defender couldn't match or use a stiffarm to beat the tackler.
If you're going to use everything, if there's no explanation of how a player made a play or was beat, you lose cause and effect and we're back to square one.
