Chargers rookie Keenan Allen makes the regrettable decision to wear Raiders hat in public

That happy gentleman sipping on a cup there at right is Keenan Allen. He's living the high life right now, enjoying his status as a newly-minted NFL draft pick. Problem is, he's a draft pick of the San Diego Chargers ... and that there is a Raiders hat on his head.

Rookie move, KA.

This past weekend, Allen was trying a little social-media outreach, recording himself on Vine visiting an In-N-Out Burger. And, as so often happens when athletes get unfiltered access to the public, things turned ugly.

Now, it's generally good form not to in any way endorse your competitors; if you're a Coke spokesman, you don't want to get caught drinking a Pepsi, for instance. But you can figure that Allen, who went to college at Cal, might be a Raiders fan from way back, and almost surely owned the hat before he was drafted in the third round by that bolt-oriented team to the south. Reasonable mistake, right? We can all agree that it was a simple oversight, can't we?

Of course not. This is NFL fandom we're talking about here. Chargers faithful saw the hat and absolutely went ballistic. Lob Shots compiled a few of the best Twitter responses. Some of the lines we can actually share:

"if that's post draft, that kid is an idiot. I won't be rooting for him." -@habitualistic

"Typical San Diego! If he wore that in Denver he would get destroyed!!!!!!!!!!!!!" -@dnel0780

"Welcome to San Diego. Now burn that Raiders hat" -@crackpotjack

You get the idea. Allen deleted the Vine and took to Twitter to express his regrets:

Of course, the fans didn't let it go that easily, with one replying, "Shouldn't have happened in the first place." Another fanned the flames of the grassroots burn-the-hat movement, which would win Allen pretty much the entire city of San Diego but put a price on his head in Oakland.

Fun stuff, huh? When do we get to playing actual games again?
