Spring practice is a time for unbridled—and maybe even unfounded—optimism, but a select bunch of college football teams are guaranteed to improve in 2016.

And they'll be better where it matters most: the win column.

For some programs, that means crawling out of the Football Bowl Subdivision cellar. They could double or even triple the number of victories from 2015, an impressive step after mediocrity.

Others will compete for conference and/or national championships, reaching a level the school hasn't achieved in more than a decade or simply improving on a disappointing year one season ago.
