No it's not....it's not arguable in the least. FACT is, the Titans RBs used it previously. How the hell is that arguable?
It is arguable who came up w/ it first.
Which is kind of dopey...getting riled up about a nickname you didn't come up with in the first place is just...well...weird.
Didn't matter though - the fact that it got used for us that year and then the jags the next year was enough to get people terribly riled up.
Come up with something original and then complain when someone cops it...then it'll be valid and you can get a twisted ass over it.
