The changes will change the method you play zone coverage. Apart from being able to offer more choices in the zone assignments you can offer to your defensive Madden 25 coins players this year, they'll also be able to cover these zones more effectively than they did in the past. For example, the middle of the field was typically a place for players to get an easy run last year, as defensive players would typically protect receivers for a short period before letting players run loose after they had reached the edge of the zone he was assigned. However, this year the defense will be able to stay with the receivers more closely, perhaps even mirroring the routes of receivers on All-Madden and will often try to run over the lines in the event that the quarterback isn't vigilant.
Man coverage also saw an improvement in the coverage this season, and although the notorious corner routes for TE will be a major issue for a number of unfortunate linebackers on the edge of an island, it's refreshing to know that it's at the very least feasible for better players (like Von Miller) to remain with their team and forcefully wrestle the ball away from the hands of players on occasions.
While on the opposite side of the ball, the offensive line has been undergoing changes to avoid some of the frustrating situations when logic seemed to go out of the window in past. You've probably had to be running the ball with a blocker right in front of you only to witness him unexpectedly pass an oncoming defender and then leave you in an buy madden coins avalanche in awe of the reason that the fat jerk wasn't able to properly protect you was way too often. In the coming year, you may have some instances when a lineman fails to give you the player you'd like but blocking your blockers at the very least seems natural and trustworthy enough that you're able to trust them.
