All angles would say SF is the play. Most of the bets appear to be on SF though, 70% in some places yet the line has held steady at 3 and even gone down to 2.5. Lane Johnson's health will be a huge issue as well as Cunningham. If they can't block whoever (Bosa/Young) lines up over RT they're in trouble. Linebackers are very important in stopping SF. On the flip side All-Pro S Hufanga being out for the year is a huge blow to SF's secondary. Goedert also somehow miraculously may play although doubtful.
As of now I'm on Philly and quite large. Public sees this as easy money, Eagles are barely beating teams is the narrative, "they always get lucky" which is absolutely BS for anyone that watches the games. Philly knows how to win, there's a lot to be said about that. And as much love as Purdy gets, I'd back Jalen 1000 times in a big game.
