The line at my book opened at Chiefs -1, lots of money coming in, I got in at Chiefs -1 but it cost me 15. Line just moved to Chiefs -1.5.
Niners pass D is ranked second, but it's more to do with their rush than their coverage, New Orleans proved that. If Mahomes can get enough time, he'll shred them. I'm hoping to see max protect and let Hill, Hardman and Watkins fly, one will be open.
I think the Chiefs O line play is going to be the determining factor in this game.
If the Niners are forced into passing, it could get ugly. Garappolo's 2-1 TD/INT ratio is horrible, they'll probably pay if they're forced into catch up mode by the pass.
Lots of similar stats between the teams, Niner's definitely have the advantage running the ball. Chiefs special teams are quite a bit higher rated than the Niners.
Right now, I expect a high scoring game, with a special teams or defensive TD by the Chiefs to be the determining factor. This could change if Tyreek gets in trouble in Miami before the game...
