Donning sunglasses, Panthers defensive end Greg Hardy said his name was "Kraken" and that he attended Hogwarts during SNF's player intros. But the nickname wasn't totally random.
Back in the summer, Hardy gave nicknames to Carolina's defensive line. As a whole, they are "MonStrz Inc." but each player has his own title. From the Charlotte Observer:
Hardy has long called himself the “Kraken,” but has added names for Charles “The Loch Ness Monster” Johnson, Kawaan “Minotaur” Short, Star “Hydra” Lotulelei and Dwan “Phoenix” Edwards (because Edwards keeps “rising” out of the ashes to resurrect his NFL career, Hardy said).
There you go. Greg Hardy likes nicknames.
