Don't overthink this. Just ride New England until proven otherwise. The Patriots have covered 71 percent of their last 65 games! Bill Belichick should enter the Hall of Fame just on that number alone. 
A lot is being made of the Patriots going up against the most dangerous dual-threat QB in the NFL in second-year man Lamar Jackson. Turn it around, though. Jackson is going up against a Patriots defense that could be Belichick's all-time best. The Patriots are surrendering an NFL-low 7.6 points per game. They rank No. 2 in totals yards and passing yards. New England has intercepted at least one pass in each game and rank first in interceptions and sacks. 
Oh, yes, the Patriots have won the last 21 times they've gone against a first or second-year QB. 
John Harbaugh has been tough following a bye. The Ravens, however, haven't been a strong home team failing to cover in their past six home contests.
