This game is basicly a pick em' game for good reason. Both of these teams are capable of beating the other even if the other team plays well.
Sure, one team could have a bad day and it could be a lopsided victory, but these are two quality teams.
The 49ers are a complete team on both sides of the ball.
The Chiefs became a complete team when they got healthy and the defense emerged in the second half of the season...and they have the best quarterback on the planet right now.
This should be a great game if both teams bring their best.
