Solo Franchise?

Okay here’s the deal…….it’s been a long time since I played madden (madden 15 to be exact) but here is what I’m trying to accomplish, I want to create a player (quarterback) and then I want to put that player on the Seahawks roster and then play as the Seahawks through preseason and then onto the regular season against the AI. I don’t want to control both teams, which is what happened when I tried to figure the whole franchise thing myself 🙄😑 This stuff is a little overwhelming to me and I was just wondering if maybe someone here could point me in the right direction. I would GREATLY appreciate it 😁 I already tried looking this stuff up on the internet but with not much success. I just want to play against the AI 🤔
