Great Question...ESPN will be nuts. If you are someone who likes shoulder to shoulder nuts, then this place will be your ticket. You did not mention transportation, so if you have a car, We stay in the area 3 months and know a lot of the places outside of Disney. They will all be busy, but a couple of places jump out at me as fun.
Town Tavern in Celebration...Bar area is small intimate with one huge TV and several right behind the bar. Great food, one of our favorites.
All of the Buffalo Wild Wings places have tons of TVs and seat a lot of folks. We check out Big Ten Athletics there a lot in the winter.
Sneaky fun might be a British Pub that does lots of soccer but Super Bowl will be on the TV that day. Devanny's Pub, right at the end of 192 West, about 5 miles from Disney. Fish and Chips, Shepherd's Pie, MMMMM
Miller's Ale house will be packed, too as they are one of the most popular and reasonably priced restaurants in the area. They areon 192 west of Disney just across street from Target or just outside Disney far east entrance past Downtown Disney (left of Apopka Vineland and then left in a block or two.) Also if go out the east entrance and go straight into the Lake Buena Vista hotels and restaurants there will be 20 places with TVs and food.
Also, if have a high Def TV in the room, the hotel might be a great idea!!
