In Madden leagues I have seen punt blocks, and I've seen and done a few punt returns and kick returns my self, both aren't really that hard. And thats on All Madden too. I even had a game with 4 total kick returns. Another game with 2 kick returns and a punt return, again on All Madden.
But EA is stupid with the microtransripoffs. Its all about Madden Ultimate Team, EA will keep promoting that stupid mode to the moon just because you cant win a game or compete without buying packs, when anyone you play online has a full 99ovr team. Hence why no one plays it online besides the guys who paid for 99ovr teams.
