Here's the thing... Define "rival"? (and no we're not using Wikipedia, but
Winsipedia
I've seen some people say "any game series you've played regularly"
I've seen some people say "any game series in which you've played regularly and have been reasonably similar records in history".
So would I consider Alabama a rival for USM? By definition 1, yes. By definition 2.. Nope.
Sort of like.. most USM fans consider Tulane a rival (by definition 1, makes sense, but by defintion 2 - 24-9 w/l record for USM? Not a rival?)
Would it include Historical rivalries? If so, I'd include any of the Louisiana schools that go back to the Great Gulf Conference. But nobody seems to consider LaTech a rivalry for USM. (52 gamers, with a 35-17 Win/Loss record?)
Is it a team from previous conferences that we had to play a lot? Tulane, Memphis come to mind.
Is there a trophy involved? This would put LaTech back on the list. (the Dix), Memphis (black and blue bowl), Tulane (Battle of the Bell)
So "define" rivalry for me in a full-scope and then I'll tell you...
"Is USM playing you this week? Then you're my team's rival for the week, and I hope we kick your asses".
