The National Football League has announced the official Week 18 schedule, which is often set only near season's end so that broadcasters can rearrange games according to levels of interest (or boredom in this case). When it comes to the Kansas City Chiefs, the powers-that-be got things absolutely correct.
The Chiefs always knew they were traveling to Las Vegas on Sunday, January 4 since last May when the NFL unveiled the regular-season schedule, so it's not as if the league is putting anyone out too much by not revealing the finer plot points. That said, when they finally nailed those down, they felt quite appropriate for all parties involved.
