Austin Madison is an animator for Pixar, and has worked on movies including Ratatouille, Toy Story 3, and Up. But this is perhaps his finest work: a series of sketches throughout the NFL season, previewing one or two of each week's games.

The drawings only got more detail and more colorful from there. You can see all of them, including bonus BCS Championship and World Series sketches, and quarter-by-quarter updates of the Super Bowl, at the "Fantasy Football" tagpage of his site. Here are a couple more of our favorites.
