Not to just ride your coattails, but the bolded is what came to mind first for me.
Pretty sure the initial tweet referenced his dad being an orthopedic surgeon for Miss St. And I don't know him, but when Luke talks about the football program, the University, and his experience...it just feels like this is what he wants.
Whole thing seems to have just blown up from some dude making connections between Luke and Heupel and the internet did it's thing and ran with it.
Always appreciate the input, and Happy Easter back to you (and all).
