How to relocate in Madden 20 is basically the same as previous iterations of the franchise. It can only be done in Franchise Mode and was added to allow players to do similar actions as the St. Louis Rams did or the Oakland Raiders.
Now, we have the Los Angeles Rams and soon to be the Las Vegas Raiders. You can do the same in your Madden game.
How to Relocate in Madden 20
In order to be able to relocate, you need to select Owner and then open up the league settings and choose "All Players Only" under the relocation setting.
If you want to relocate, start the process immediately. Head over to the "Team" tab, select "My Owner," and then "Stadium." Hit the Relocate button and it usually takes until Week 5 before you can choose your new city.
You'll have 19 cities to choose from and 17 of those have three unique team names, logos, and stadiums. From there, it's all about your style and preferences, so go nuts.
