Football, for the untold millions spend on scouting and analytics, is a simple game.

Take the Dolphins’ surprising struggles on defense. They are on pace to surrender the most points since their disastrous 2007 season for one basic reason: Drives that used to end in field goals now result in touchdowns.

“Stats don’t lie,” linebacker Jelani Jenkins said. “We’ve got to do a lot better job in the red zone. When they get down there, we have to hold them to field goals. When we do that, we have a lot better chance to win the game.”

And yet, recent history suggests it won’t get better any time soon.

The visiting Dolphins (2-3) tangle with a potent Bears (3-3) team Sunday in a true crossroads game for faltering Miami.

Chicago, with its gunslinging quarterback (Jay Cutler) and tall set of targets (Brandon Marshall, Alshon Jeffery and Martellus Bennett), usually doesn’t miss from point-blank range.

The Bears rank seventh in red-zone efficiency, scoring touchdowns on 68 percent of their opportunities, which ranks seventh in the NFL.
