The Vikings are a 3.5 home dog going into Sunday's tilt with the Lions. It's obvious the roar has been restored after Detroit's 48 - 3 dismantling of the Chefs and proof positive by Vegas making the visiting Lions a 3.5 favorite. The over under of 44.5 seems like a big number but some of the other games are up to 52.5. So much for defensive games.
