Yep, EA forgot to add retired numbers off option to custom league franchise..

And…

if you want to play an 80s reboot league I can’t change the computer team jersey when I go to play a game. I have all the teams set to alumni teams they should give you the choice to change it. 
(or am I missing it somewhere?)

it’s not very accurate to be playing 1987 oilers and you play against the Canucks in 2022 jerseys.
