I HATE it when I feel like I am going along with the crowd. lol
That said. I give the slight edge, although the final score might not be so close, to the 49rs. On paper this is a classic and close match up, here's why I give SF the edge. In both play off games the Chiefs dug themselves a hole, a HUGE one in the game against the Texans and a smaller one against the Titans, neither team being of the caliber of the 49rs. Patrick Mahomes is a fucking magician, but even he can't launch a comeback if the 49rs don't give him the ball back.
In many games getting off to an early start is not as important as in others, I think in this game an early start is HUGE. Kansas City wants this to be a shoot out between Mahomes and Garoppolo, who of course is no slouch himself. SF wants Mastert to have another 200+ yd game, control the clock and keep the ball out of Mahomes hands for as much of the game as possible.
I can see KC loading eight men in the box early to force SF to throw the ball, that of course will leave "someone" in single coverage and Garoppolo is too good for that strategy to last the entire game.
My prediction, SF low forties, KC high twenties. This pick of course is worth EVERY penny you are paying for it. NO REFUNDS lol
