I like the 49ers in this one, they have a more solid and consistent defense than anyone else the Chiefs have faced in the post season. I'll take a stab at a score prediction; SF 34, KC 28.
It's going to be a fun game anyway. I would have liked to see Green Bay and Kansas City duke it out. A replay of of the first super bowl would have been a fitting end to the NFL's 100th season.
It would have made for a great story but game wise kansas city would have blown them out and I think would have been boring. This will be a way better game than if green bay was in. I think san fransisco and kansas city have been the top 2 teams in all the nfl (except for baltimore) so I think the right teams are in.
