By and large there's some coachspeak, but I have found them interesting. I was particularly looking forward to Warinner, though I didn't feel like I learnt a great deal about his evaluation of the kids and new o-line philosophy. There was a bit about making complex ideas simple, so here's to hoping that works out.
What has stuck out to me so far were the Partridge and Jay Harbaugh installments. Partridge spoke on his recruiting philosophy and how much time it takes with his recruiting style--something like 2-3 years for a coach to build up relationships. From Jay's interview there was a brief glimpse into last year's problems with the offense from a coaching standpoint, with Jay talking about arrogance getting in the way of results and working relationships--a not-so-subtle reference to Drevno's time on staff.
Anything you've found interesting?
