Here's one thing we know about this playoff game between the Miami Dolphins and Kansas City Chiefs: it's cold.
Not just regular cold. Frigid cold. Penguins wearing parkas cold. Not a great environment for human football players to perform their best.
And each team needs some level of best to make it to the next round. The Dolphins need Tua Tagovailoa to show up and be the top tier quarterback he's capable of being. They need Jaylen Waddle and Raheem Mostert, who have been sidelined with injuries, to perform well in concert with Tyreek Hill, who also needs to have a big game.
