No, however we did get another book of gobbledygook . . .I know where this line of questioning is leading, so let me cut to the chase. When I was 18 years old I have a cousin who had been an All SEC 2nd team All American offensive tackle. This cousin also had a microbiology degree from Ole Miss. His first old lady used to tell everyone at the family reunion her husband wasn't gonna waste the rest of his life chasing football as it was a poor man's way to end up with a life changing handicap. He was projected to be a mid 2nd to early 3rd rounder, but through his wife told NFL scouts he was going to college & get his PHD.
Long story short, he ended up leaving that woman & pursuing what he loved the most which was football. So at 30 years old he was the head coach at Itiwamba Jr. College. I was 18 years old & started my own subcontracting business right out of high school. I made 14,000 dollars more than he did at 30 my first year floating sheetrock, painting & hanging wall paper. So guess which direction I chose to go with my life. So, when you ask for credentials that is a bull crap cheap way to justify a lazy ass situation by waving a sheet of paper.
The best coach I ever had who taught me more than anyone else in my lifetime about football except George Allen was roofer. That roofer happened to start at guard & was an All American on all three of Bud Wilkinson's undefeated teams in the 50s. He was also a Student graduate assistant on the next team, but got his girl pregnant & had to out in the world to make a living. The moral of the story is you can love something, but life gets in the way of pursuing your desires. So yeah, I have no college, or professional coaching credentials. It was a choice I made over 40 years ago & haven't regretted it until the past 10 or so years when coaching salaries have gone to the moon. If coaches were making then, what they are now. I would have definitely gone another direction. Does this assist you in your search for my level of football knowledge.
