The quarter length and accelerated game clock affects gameplay as well, you should note. At least in my experience. When you have a low play clock, the CPU never has time to make adjustments. When I play on 9 minute no accelerated play clock, I give up 500+ yards a game on sliders I usually use on 15 minute, 14 second play clock. It also affects QB accuracy in my opinion and the game just felt faster. Like on 15 minute quarters, no matter what QB was starting, the CPU always had 65-75% completion percentages. On 9 minute no runoff, Aaron Rodgers was 54%, then the next game Alex Smith was 62%, next game Brees was 69%, next game Tyrod Taylor was 49% with 3 picks. I've just been testing different quarter lengths and play clock times in Play Now, and this has been my experience. I used to only play 15 minute, 13-15 second play clock for realism, but I think I'm going to boot up a new testing CFM and try 9 minute no runoff.
