From an interview of Gary Pinkel by Bill C (for the big SB Nation piece last week). Thought it was interesting in light of CB's obsession with Bronco's use of time.

BC: It seems like one of the biggest changes is simply speed -- your ability to make evaluations of yourself and your opponent more quickly. Every coach I've talked to who started in the '70s or '80s began by cutting up film and hanging from the big lines and whatnot.

GP: Oh, that part changed -- the technology part of the job has changed remarkably. I remember in the 1970s using splicing machines, hot splicers, putting all that film together. All that information you get now, that's changed.

BC: So when you get information faster, what fills that extra time? Do you go into more detail because of that extra time?

GP: It's just all data, and you have to determine how you're going to use it. You can get so much data on so many variables. You have to figure out what works best for you so you can make good decisions.

You can overdo it. But it's interesting because we used to have to accumulate all the data and work till 9:00 or 10:00 at night, Sunday through about Wednesday. But now all that stuff on our next opponent, we have every bit of it in place when we walk into the office on Sunday morning. We have it all.

It amazes me that so many people still work till 10:00. We don't here, but it seems like most still work till 10:30, 11:00 every night because it's just what you're supposed to do. I try to be a bit more family-oriented for my coaches.

Contrasts fairly sharply with what I've heard about Bill Snyder, for example:

He dresses predictably and practically, either khaki pants and simple collared shirt or suit and tie. He never makes any promises except to keep working hard, and ohmygoodness, does he ever work hard.

The standard work week around K-State football is around 120 hours. Once, an assistant went to get a drink and returned to a note on his door telling him he’d be fired if he ever left the building again.

Interesting to contrast given that while neither is Saban or Meyer, I would rate both as great coaches and by necessity neither has just relies on superior athleticism.
