Hi Sarah! It's absolutely not a weird question, my husband is planning our Sunday around the game too.
I can't think of anywhere right off hand where you'd be able to see the game at Epcot but I have a great alternative for you. The best place to see the game would be at the
ESPN Club which is on the Boardwalk. At the ESPN Club there are literally 100 video monitors so you wont miss a second of the game. Yep, even in the restroom you'll be able to keep an eye on the score. This place is a sports fans paradise. The food is great too, might I suggest trying the PB&J Burger. Bacon, peanut butter, jalapeno jam, a burger and a toasted buttered bun - it really can't get any better than that. If that's where you decide to watch the game, it will actually be very easy for you to get there from Epcot. You will exit Epcot via the International Gateway, which is the back entrance/exit to the park. This exit is down a path between the United Kingdom and France pavilions. Then it's maybe a 10 minute walk to the restaurant. You will be able to follow signs to get there, you'll want to look for the Boardwalk Resort. You can always ask a Cast Member to point you in the right direction as well.
I hope you have a fun time. Let me know if you have any other questions.
