Team builder Multiplayer

Why is it so difficult to play a Dynasty on a your own Console with Multi-player and Teambuilder? My brothers and I get together a few times a year and all we want to do is create our own team and build a Dynasty with a created team.  We have no desire to play anyone online, just see how many seasons we can run thru before we get back to the reality of life.  We have been doing this since 2003 or so.  So we were excited last year the game was back only to find out we can't even play together with a created school after hours of creating our old school we use to run with.  What's the big deal?  Can't you just unlock this if you are in a private Dynasty mode? Got the game again and still the same thing?  Please fix this.  The controllers show up but you can't select either team..... Come on EA?
