Biggest strength: The Dolphins' most consistent strength has been a stout defensive line led by Ndamukong Suh and explosive pass rusher Cameron Wake. At the peak of his powers, though, running back Jay Ajayi has carried the team to victory -- just as he did with a 204-yard performance versus the Steelers in Week 6. If the Dolphins are going to pull off the upset against an improved Steelers squad, they need the offensive line to win the battle at the line of scrimmage while Ajayi repeats his tackle-breaking heroics in Pittsburgh.
Biggest weakness: Ryan Tannehill will not be medically cleared for Wild Card Weekend, leaving veteran signal-caller Matt Moore as the Dolphins' starter. Although Moore earned AFC Offensive Player of the Week honors on 18 passes exploiting a generous Jets secondary in his first start, his limitations have been apparent the past two weeks. He misfired on a series of throws just before halftime in Buffalo, costing the Dolphins a pair of field goals in the two-minute drill. His inability to stretch the field was evident in last week's loss to the Patriots, resulting in just two scores on 10 possessions. Can he stand toe-to-toe with Roethlisberger?
