No! You will be able to add teams one at a time, or as many as you want until you reach your limit of five teams.
To add another team to your list, click on the ADD button in the window of the team you wish to add. You will be given a chance to add that team to your list, and also confirm the addition. Please be aware that National and Local blackout rules apply.
You can also click on the Add more teams button on the top of the League Pass Broadband Screen until you reach the maximum five teams.
