won't solve it. Think about it this way, they have to release the game every year and they can't spend all their time working on a patch for the current game, they have to at some point stop an move all recourses towards the next game and it so happens that in football there is a transfer window at the middle of the season where players are allowed to move around and it's the perfect time for SI to put out the last patch to update the data base and fix what they are able to fix and move everything to the next game. The only way they would go back to working on the current game after the winter patch is if there is some issue that makes the game literally unplayable like crashes.
I don't blame them for that, every yearly release game has the same issue. some things are easier to fix and don't require as much testing and somethings are not, that is the nature of software
