Reddit user dybuell (real name Dylan Buell) just released some fantastic schedule posters for every FBS team. Here is the link to the entire set, and here is the link to the Big Ten set. I cannot embed the Michigan ones due to the licensing agreement. However, if you go to the Big Ten set, you can download them yourself by opening the desired image in a new tab, right-clicking, selecting the image size you desire, and clicking the download link.
He also made a guide detailing coaching changes, conference changes, etc. Here is the link to the reddit post. I asked Dylan for permission to post this, and he kindly obliged. I hope you all appreciate his great work as much as I do!
