After growing up in Baton Rouge, Louisiana, New York Giants star receiver Odell Beckham Jr. attended LSU for three years.

So he bleeds purple and yellow.

Prior to the Tigers’ showdown with Alabama on Saturday, a few Crimson Tide fans hung a banner that said “Finish What Katrina Started.”

The school took action, and it was removed.

Hours before the game, Beckham posted an Instagram picture of LSU running back Leonard Fournette with this caption: “Katrina never broke us, it made us savages... @_fournette7 #4ThaCity #Follow”

Boom.
