Baltimore has certainly been living right this year: at LV, vs KC, at DET, vs MIN all certainly could/should have been losses
Yep. I mean you have to give them credit because good teams find ways to win... but they have pulled the proverbial rabbit out of a hat several times this year in games they should have lost.
According to that ESPN "Win Probability" calculator, at different times in those games:
Chiefs had a 84% chance of winning near the start of the 4th quarter
Lions had a 70% chance of winning with 26 seconds to go in the game
Indy had a 91% chance of winning in the 4th quarter
Vikings had a 85% chance of winning around halftime
And the Ravens won them all... good for them but that's a hard way to make a living.
