We can only chalk it up to Harbaugh being Harbaugh. Or, maybe he was trying to stay out of the sun? Who knows.Here's the video, which is as funny as you'd expect it to be.I have a strange suspicion Harbaugh just created a new meme that will be used for generations to come.

Jim Harbaugh is a social media superstar, not because he's online all the time -- that'd be wild given that he's an NFL coach -- but because fans love to focus on the quirky guy at the helm of the Los Angeles Chargers (I don't know, maybe it's because of the khakis ).

Former Michigan standouts Jabrill Peppers and Jourdan Lewis can attest to that, and they jokingly hypothesized that Chargers wide receiver Mike Williams abruptly retired because he couldn’t stand another day of Harbaugh training camp.
