Whether you prefer the conspiracy theories or just enjoy the sheer ridiculousness, the story is a cracker: ground staff at the Levi's Stadium managed to mark up both end zones as the Broncos'. The error was rectified, of course, but not before it was spotted by stadium-goers this week and, if you squint, you can still see a faint 'B' under the Panthers paint. This one's sure to get a mention.
