Final Grade: B-
The unit struggled as a whole in the first half, unable to generate much pressure on Tannehill and allowing receivers open lanes through which to run.
They stifled Reggie Bush for the most part, minus a missed tackle or two. He finished with 17 carries for 67 yards. The Cardinals allowed their first rushing touchdown of the season, a second-quarter one-yard plunge by Dolphins fullback Jorvorskie Lane.
The second half was brilliant from the defense. While they were unable to create any turnovers in the first half, Arizona manned-up and forced four from the third quarter on—including a Kerry Rhodes interception in overtime, setting up Feely's game-winner.
A bit unexpected, the secondary struggled to contain the Dolphins top two receivers, Davone Bess and Brian Hartline. The two combined to catch 19 balls for a staggering 376 yards and one touchdown. Hartline caught 12 for a franchise record 253 yards and hauled in the 80-yard TD that shifted momentum back to Miami late in the fourth.
Overall, the defense still has things to work on, and on a short week and traveling to division rival St. Louis, they need to get it together in a hurry.
Fourth Quarter: B+
The defense allowed a touchdown following Kolb's interception. Other than that, they forced two three-and-outs, two turnovers and sacked Tannehill twice. They were brilliant.
If not for one 80-yard mishap, the game would be over. But we're in overtime.
Third Quarter: A+
The defense we all expected to see showed up in the third quarter. Starting with a bend-but-don't-break drive that saw Dan Carpenter miss a 51-yard field goal, the Cardinals nearly had three interceptions in successive drives.
They came away with only one, but the unit is playing much better compared to the first half. The pressure has been non-existent still, but the run defense has stepped up.
Second Quarter: F
Rushing. Passing. Catching. The Miami offense did it all in the second quarter. They were unstoppable. Reggie Bush gashed the front seven and Tannehill completed 7-of-11 for 133 yards.
Cornerback William Gay is having one of the worst days of his career, certainly of his Cardinals career. He hasn't adjusted at all yet. Bess burned him in the first quarter, then Brian Hartline did the same in the second.
He went back to guarding Bess, and Tannehill found him wide open down the middle following Kolb's interception to set up a 27-yard field goal from Dan Carpenter.
Dolphins 13, Cardinals 0 at the half.
First Quarter: B-
Rookie quarterback Ryan Tannehill completed 8-of-10 passes for 86 yards in the opening quarter and hit a wide-open Davone Bess three times for 51 yards. William Gay has struggled in covering Bess. If Gay doesn't adjust quickly, the defense may find itself in a hole.
Reggie Bush is playing, but he was stifled in the first quarter, carrying the ball four times for nine yards.
Pressure has been inconsistent, with Sam Acho recording the only sack thus far.
