Defense is the key
Need a quick football primer so you know what you're talking about Sunday? To sum it up in a few words, the game comes down to one of the best defensive teams in the league (the 49ers) facing another pretty good defensive team. Linebacker Patrick Willis (pictured, making a tackle) and the 49ers were 2d in the NFL in points allowed, while Baltimore was 12th. The game should be physical and it could be low-scoring. The 49ers are slight favorites in Vegas.
