Mauer & Polamalu For Head & Shoulders?

They kept showing this commercial during the Knicks game and it was pissing me off. Why are Joe Mauer and Troy Polamalu doing a shampoo commercial together? What do the two have in common? Polamalu's got the hair, but is Mauer's hair really that special for them to make a nonsensical ad together? Who are the ad wizards that came up with that one?
