This is a very big total. Certainly superstar QB's Patrick Mahomes and Lamar Jackson are capable of producing huge scores. But a lot has to go right to buck this large of a total.

The Ravens run a lot. Even without their two top running backs, injured J.K. Dobbins and Gus Edwards, their game plan is going to remain the same - stay on the ground to keep the ball away from the deadly Mahomes. The Ravens are ground-oriented. That's who they are. Lead running back Ty'son Williams is untested. Latavius Murray is a straight-ahead runner perfect for the Under. Recently signed veterans Le'Veon Bell and Devonta Freeman are both washed-up.

The Chiefs' defense gets reinforced this week with the expected return of star safety Tyrann Mathieu and respected pass rusher Frank Clark. The Ravens' offensive line gave up a lot of pressures and three sacks against the Raiders last Monday. Chris Jones is an elite pass rusher who the Ravens have to game plan against.

The Chiefs' have a new offensive line with three first-year starters. The strength of that line are veterans Orlando Brown Jr. and Joe Thuney. Brown and Thuney are better run blockers than pass protectors. So the Chiefs could be running more than usual especially if they build up a big lead.
