Super Bowl Sunday! It’s here at last, the national holiday when we’re forced to sit through football in order to watch so many beloved ads ... and Taylor Swift appearances, of course. For the twelfth straight year, Yahoo Sports’ Liz Roscher and Jay Busbee are here to escort you through the dizzying array of celebrity cameos, awkward jokes and heartstring-tugs of this year’s waves of ads, updating live as they air.

As always, we grade ads on a completely subjective, utterly biased, totally nonscientific basis, and all grades are final. Feel free to contribute your own takes below. Now ... on with the ads!
