Every team needs a rival - a team you love to hate, someone who tries to occupy your space. For Pittsburgh, that would be Penn State; for Va Tech, it's Virginia. A few teams, like Florida State, have 2 rivals (Miami and Florida). So, who is that rival for Boston College? I have some theories, but I wanted to go straight to the source.
A Syracuse fan might suggest that they are your rivals, and there is something to that... but, I have to list the Orange as a secondary BC rival. Call it a gut instinct.
Va Tech is something of a rival for Boston College as well. Those games with Matt Ryan were epic! Still, a true rivalry is eternal, but the Hokies/Eagles rivalry feels like 2 teams which just happened to be battling for the championship - not a long-term enmity.
So, which team occupies the same space as BC? I would think it would have to be a private school that plays big-time football. Probably have to be a religion-based school too, preferably Catholic. If they play home games in the Boston area, so much the better - LINK. Oh, yeah - it helps if you guys hate 'em.
This is my take - what's yours?
