True that there are no permanent TVs in TSL. I have seen on this board where YC added a special celebration for the game. Not sure if boarding day is too soon to have developed a relationship with staff where they'd want to accommodate fans of American football in a special way. Also, that first day might be too hectic with all else going on. (This is when the European-style of boarding at multiple ports may have been an advantage.)
Just a thought -- if there are enough B2Bers interested, maybe it could have been pre-arranged? I don't know if YC Director Pepe is a football fan, but I do know that is very interested in keeping his YC guests happy. 🙂
