Consider this. Up 21 in the 4th, the Dolphins have to score three times straight and stop the Ravens two possessions in between. You run the ball 6 times on 2 possessions and punt both times, that's about 4:30 off the clock if executed to maximize clock usage and some hang time on the punts. Now the Dolphins have a little over 10 minutes to score 3 TDs.
Play 6 or 7 DBs with 2 or 3 deep (like ACTUALLY deep) on every snap, force them to go underneath more, and every tackle is another 20+ seconds off the clock. Even if they dink and dunk perfectly for the whole quarter and tie it... chances are that last possession of regulation is the Ravens and starts with very little time on the clock. You're then trying to kick the FG or taking it to OT.
It takes serious game mismanagement to blow the game in the manner that the Ravens blew it yesterday.
And to LOSE the game, they have to score 4 times, making the loss even more indefensible. Time for Harbaugh and his staff to man up and put this atrocity right where it belongs.
