re: “Roll Tide” on deck to be cancelled?

Even the history professor they cited said there's no connection.
It's pretty well-established the nickname came from the Auburn game in 1907. Every sports historian will say that. Newspaper accounts back it up.

While "War Eagle" and LSU's "Fightin' Tigers" have a direct connection to the Confederacy, there's zero links of Roll Tide to some random civil war ship.
