Just don't see SF losing this game at home to a terrible Giants team. I like my numbers on the other 2 on the good side of the key number 3 in both.
SF -.5/Seattle +3.5/Dallas -2.5
49ers were 14-1 last 15 at home, in the one loss was to the Chiefs. Purdy has a long way to go, and I had very small concern with Aiyuk out, as he has shown he is Purdy's favorite receiver. That said Giants have many of the same problems as New England, very bad OL, and very limited Wrs… Giants actually worse than the patriots, and that's saying something. Big advantage in not asking SF to cover 10.5, just need them to win the game at home, against a limited poor football team.
