If people are 50/50 on this they need to look at the pluses and minuses. Of course, it's not really 50/50 since the hoop game should be a blowout in Cuse's favor but it is live and the football game is against the 2nd best team in the country and it's on TV.
Both games end around 6:30. Hopefully the dome will have some TV's available for football watching, but if they don't I think a good option is going to the game and if it is indeed a blowout and the football game looks good at halftime, just go down to Marshall Street to watch the end of the football game.
Or better yet, make friends quickly with someone who owns a private box at the dome and then you can have the best of both worlds.
