I was in a well ran online franchise for a couple years but my personal life was getting to hectic to really put the time into it that was needed. Ever since then a buddy of mine has been practically begging me to get him in a league because I always used to talk bout how much fun it was....thing is, I don't fully think he understands the amount of time people put into these online leagues, I keep saying it isn't just casual play, you have to be active and in most leagues you have to contact your opponent, and get your game completed within 48 hours.....he's confident he can do it, but I'm skeptical, is there anyone we can have Co-owners on one team? Like can Robby87 and Scooter16 own the Rams together?.is that even possible? Like if I was at my place I could just play the games or if I'm at his place or I can't play a particular weeks game, he can play it at his place?

No I don't believe so. Only option would be for you guys to share the same account and whoever is playing sign in on that account on their own Xbox
