Sir. You disqualify yourself when you say what defense are we running and then say "I want to know how the D will be called and played in various situations". That's not what we're running, that's not even something someone can answer including Sanders because there are a million things that go into those choices in real time during a game besides the weekly game plan itself. And at no point has a soul including myself said we know that, you just aren't comprehending it.
You at the very least sound like you played ages ago, and I don't mean that as disrespect but modern football seems to be lost on you. But name dropping people you are acquaintances with as a show of your own credentials is not something people do if they do have real credentials. Just like people with money don't need to say I have money. You are not them and their knowledge doesn't magically transfer to you. I know a handful of power 4 HCs, Coordinators, and position coaches, staffers, agents, etc but that doesn't make me special. I did play I was a RB though I could have and should have chosen Safety. I also train athletes, I have been a DB coach and Co-D coordinator, OC and HC, I break down practice and game film and opponent scout. Also unless I'm misremembering the conversation, the DC didn't play college football, he was a student coaching volunteer I believe. So if I am right then he is certainly less knowledgeable than you, yes?
Typical of today's world, people have questions and someone who has direct answers can tell them what defense is being ran or that UM is encouraging recruits to graduate and enroll early starting with the 28 class because of the 5 in 5 rule, or that UM themselves knows there are facilities deficiencies and they're already planning to solve that... But instead of being thankful to not have to wonder anymore we instead decide we know better because we donate money and/or have shaken some hands and that makes us special. Going to now go back to just being a parent, reading only, and keeping my simple info to me and watch everyone argue and flounder without a clue. Crazy stuff here.
