Who said Brian Kelly wasn't a culture fit in Baton Rouge?!?
LSU's newest head coach -- who was born and raised in Massachusetts -- suddenly has the whole southern thing figured out ... showing off a shocking new accent while speaking with Tiger fans at a basketball game on Wednesday.
"It's a great day to be a Tiger," Kelly said ... sounding more like a guy raised on gumbo than New England clam chowder.
"I'm here with my family and we are so excited to be in the great state of Louisiana. But more importantly, to be with you great fans and to be part of what is going to be an incredible ride here at Louisiana State University.
