Jerry Glanville says he's still coaching in his 80's because you can only take two things into "the box" when you die.

Jerry Glanville has lived the kind of life most coaches dream of.

He's spent time around major college football as an assistant and coordinator, worked his way into the NFL as an assistant, then coordinator and eventually head coach with the Houston Oilers and Atlanta Falcons. 

Since parting ways with Portland State, where he was the head coach from 2007-09, he took nearly a decade off before resurfacing in Canada as the Hamilton Tiger-Cats defensive coordinator and has had stops in the XFL and Spring League as well.

Heading into this fall, the 83 year old accepted a Division II defensive coordinator job at Northwestern Oklahoma State under head coach Ronnie Jones.

What's a well traveled veteran of coaching doing still coaching ball well into his 80's?

Well, Glanville was asked that recently on NFL Network and he provided quite the answer.

"Well I tell everyone - preachers preach, and coaches coach. You never really quit coaching."

"If you can help one player be better than he was yesterday, then you jump out of bed and you run to work. If you can help one guy just improve a little bit, that beats all the money you could ever make."

"When you crawl into the box, and they put dead men in a box, you only get to take a couple things with you, and it's not money, it's your integrity and who you've helped."

What a great sound byte from a coaching veteran.
