Did you hear what happened to Jon Snow? If so, shut up about it. Some of your teammates aren’t caught up yet.

That’s the word around NFL locker rooms, where Game of Thrones spoilers threaten to turn teammates against each other like House Lannister and House Stark.

Kevin Clark of the Wall Street Journal reports that several NFL teams have a camp of players who are caught up on the hit HBO show and watch every Sunday night, while other players have just started watching and are stuck in a time when Robert Baratheon sat on the Iron Throne and Daenerys Targaryen hadn’t even earned the title Khaleesi of the Great Grass Sea, let alone Breaker of Chains and Mother of Dragons.

That means there are disputes about whether it’s OK to discuss Season 5, or whether being a good teammate means not spilling the beans about what the High Sparrow did to Cersei. Washington offensive lineman Kory Lichtensteiger said that if you know nothing and don’t want to hear spoilers, it’s on you to get caught up.

“I’ll wait a couple of days,” he said. “But I mean, if you haven’t watched it by then, close your ears. Earmuffs. I want to talk about it.”

Steelers linebacker Vince Williams, however, said the show is too complex for casual viewing, and he hasn’t had time to sit down and watch it with the attention it deserves. That means Williams wouldn’t know Daario Naharis from Ellaria Sand — and if any teammates spoil it, they’re going to have a problem.

“You have something going on in the South, the North, the Westeros and all of these conflicts have one main overall theme,” Williams said. “Do not tell me what happened. . . . I dare anyone to spoil it.”

It’s easy to see where Williams is coming from: You’d have to be as cruel as Ramsay Bolton to think it’s OK to spoil a teammate’s favorite TV show. On the other hand, asking Game of Thrones fans not to talk about what happened is a request that’s sure to be ignored like Princess Shireen’s pleas to Stannis.

It would be nice to think these teammates could find a way to compromise. But when you play the game of thrones, you win or you die. There is no middle ground.
