I haven't researched it extensively, but it sure seems that rushing offense has been made ineffective. I have multiple teams, and noticed none of them run the ball very well any more (and a couple have great OLines.)
Running the clock out? Forget about it. Lucky to get 2 yards per carry, punt on 4th & 5 and burn less than 2minutes of the clock. I've experienced this on both ends - protecting a lead and forcing punts while behind.
I suspect the recent update has something to do with it, and just now really noticing the trend across multiple leagues.
