That's great news. I've been thinking of tinkering with penalties a bit as well to mainly get more out of the game. The OL/DL interaction is left wanting just a tad, and I agree the DE and LBs should be making those plays. I can imagine such great interaction and animations that way.
I think I will probably do that for the next Version 21 set, and address QBA on AP a tad. Also need to get those DPI's back, but not to the point it makes things too easy on the threshold.
Subtle adjustments, but version 21 should take this to the next level.
