Seattle +3.5
I have not seen SF play a complete game since week 1 and to be laying more than a FG on the road seems silly to me. Seattle played the worst game of the season last week and maybe looking past the Giants cost them. I like what Coach McDonald did vs Purdy last year with the Ravens holding him to a 42.6 passer rating and he threw 4 interceptions. Purdy excels vs zone defenses and not so much vs man. McDonald runs a lot of man coverage. Seattle D is not Baltimore but they looked good early and hopefully get some more injured pieces back tonight. Seattle gets back to the run game with Kenny Walker because SF run D maybe still the weakness with Hargrave out. I have seen more good from Seattle this season so I am expecting a bounce back at home.
Good Luck.
