While Syracuse is likely BC's biggest rival by default, there just isn't much juice (no pun intended) there. Very rarely over the past 30 years have both teams been good at the same time. Cuse fans probably considered WVU, Pitt, and Miami as bigger rivals than BC during the Big East days, and PSU before that. Basketball has been totally one sided, though I understand this was a football post. Removing the four ACC/SEC season ending games, I don't understand how the ACC doesn't have BC-Syracuse, Miami-Pitt, Duke-Wake, UNC-NC State, and UVA-VT annually on Thanksgiving weekend. If that were the case, and if BC and Syracuse improved to their programs to a point where the games are generally evenly matched with some level of importance, the rivalry can grow, but for whatever reason, the ACC keeps fiddling around with the final weekend schedule
