College football's offseason calendar has incredibly reliable benchmarks for letting you know just how much time there is before the season. You've got National Signing Day in February, spring football in March-April, move-in day in June, and stupid arrests season in July (hopefully not involving your school).
Also in July: conference media days, media guide releases, and ... POSTERS! This year, we were given wallpaper versions of Mizzou's 2015 posters to share. They're pretty great.
The Evan Boehm one is particularly wonderful.
These are pretty big files, so if you're into the "saving as wallpaper" thing, they should work beautifully as wallpaper. Enjoy.
