Greg Mattison was coaching in the Big Ten before Ryan Day was born.
I think that's neat.
That's about it, though. At a certain point cumulative years stops being impressive as a coaching feat and more of a statement about how you can fall ass-backwards out of a coaching tree and hit like five more jobs on the way down as long as you've been up there for 20 years or so and made enough friends along the way.
Which is not a comment on Greg Mattison the coach! We've talked about his schemes and his potential, and he's proven over a very long career that he can construct some pretty formidable defenses (last game against Ohio State notwithstanding).
