Change Team

Hi, 

I am totally new to Madden. I just bought and downloaded the game and wanted to play solo in the ulitmate team section. I was ask, which team i wanted to play and i selected the wrong one. Now I cannot find an option to change the team (like I can change line-up and players but its still shows "Houston Texans" as the team). Is there no way to play as a different team? I could also reset the entire ultimate profile if this helps (did not played that much there so far).
