Really don't see that. The running and general movement of players is very different. Doing a lot of running plays and you'll see some very plain differences (especially when running out of shotgun).
Yeah that comment confuses me. It is a whole new engine. I don't understand people's issues with sports games not making huge overhauls. They only have a year to develop these things, but I do think some competition in the market could help things advance faster.
I love the new RPG element to the dynasty coaches, which should make for some fun online dynasties. I am not completely sold on the recruiting yet, but that is mainly because I haven't really set down with it yet.
Ultimate team should be awesome as well
If you have 2 hours to kill and haven't gotten the game yet this guy did a full season simulation to help show the changes to dynasty: LINK
