Look, I don't have a ton to say here. The Vikings are good-to-very-good on both sides of the ball. The Browns are awful in every way. Stephon Diggs is back. Joe Thomas is out. Case Keenum has been playing like a legitimate starting QB. It's a roll of the dice every week to determine who even starts under center for the Browns.
London games always weird, but the one constant in this league is the Browns losing. With a stout defense and a lot of weapons on offense, I think the Vikings cover the 10.5.
