First things first: Are there other NHL teams besides the Penguins and Capitals?
OK, sure, in the strictest technical sense there are other teams in the league. In addition to the Penguins and Capitals, there are also the Flyers, Rangers, Red Wings, Blackhawks and… um… the Lakers. Look, it really doesn't matter. Just pay attention to the Penguins and Capitals and everyone will be happy.
Cool, so both those teams will have long playoff runs?
You know what, maybe just focus on the Penguins.
