I'm torn.
Don't want the 'niners fans to be all "we're back and we're gonna get seven before the pats or steelers," but I also really like Jimmy G and would like to see a BB protege take home the bling.
On the other side, I have strong feelings about the crying the Chiefs' fans did after losing last year's AFCCG without getting the ball in OT...duh, defense is part of the game. But, Andy Reid is apparently a genuinely nice guy, truly turned around a moribund Eagles' franchise and almost got it over the final hurdle without a true Franchise QB and arguably deserves a ring to cap off his career.
All of the obvious story lines have been played out in the media all week...keep Mahomes off the field...do to him what Tennessee successfully did to MVP Jackson by making him run laterally...get the SF running game in gear early.
I think the one intangible is that the pressure is more on KC and Reid than SF and Jimmy G. So, I'm giving a (very) slight edge to SF, especially if they run the clock and get up a score or two early.
But, i agree with everyone who says it could be a great game. Definitely taking the over.
