What were you doing in the summer of 2015? The Golden State Warriors had just won their first NBA title, the Seattle Seahawks were still complaining about Malcolm Butler's Super Bowl interception, and the Kansas City Royals were gearing up for their World Series title. That is when John Harbaugh and the Baltimore Ravens last lost a preseason game. Their inexplicable win streak reached 23 games on Saturday, thanks to a defensive stand against Sam Howell and the Washington Commanders. Yes, there were no-names roaming around but their ability to keep churning out victories does say something. No one has put an exact finger on what exactly it says but we do know it does resonate — especially with bettors. The 17-15 Baltimore victory means the ATS run drops to 20-3 but it's still another win.
