Thankfully I hadn't run into that problem in Play Now too much, but I only used a select amount of teams that were mainly the highest and lowest overall for testing. I will say this though, the ratings and low awareness I'm noticing with so many players is troubling, and imagine that's likely a contributing factor apart from coding. Guys with awareness in the 30's and 40's I don't feel should be a thing, but they do this to order depth charts and fit guys into schemes a lot. But, anytime I've set my line properly and identified blitzes well enough, the blocking has been pretty good for me. I'm on PS though so I can't speak for XBox or PC though either.
