One thing to know: What to watch during conference championships

With two great conference championship games set to take place Sunday, Mike Florio breaks down his biggest factors to watch in each game. In the AFC matchup, Florio wonders if the Broncos will focus on stopping the Patriots run game and force Tom Brady to beat them with his arm. In the NFC, Florio says the 49ers have to give the Seahawks a taste of their own medicine and play a physical game to interfere with the Seattle defenders.
