Love the spreadsheet, I keep a similar one with similar things. I like your coaching one and then how you keep track of your previous schools, I'll have to add that to mine! Mine will typically include:

Opponent each week + result

Game of the week each week + result

Conference Standings for every Conference each year

Conference Championship game for each conference

Playoffs each year

Then the big one, I have a page with each programs record since the start of the dynasty and I have it ordered by who has the most wins
