 This is Coach Mack. Welcome to Beneath the Surface, powered by Microsoft Surface. Let's take a look at AJ Brown's 57-yard touchdown here, first and 10th of Tennessee 43. Titans come out in 13 personnel, which causes Indianapolis to reduce their defensive formation. We're going to get the tight end for the Titans right going in motion. Tight end goes in motion. You can see now that it's man-to-man. And so what we've got now with 13 personnel, they know they're in man-to-man. This play action is solid protection. This is Mack's protection. And Ryan Tannehill knows that he has AJ Brown with a corner man-to-man on the outside with a deep safety in the middle. Perfect protection. This Mack's protection. Look at the great pocket that he has to throw in. Beautiful throwing lane for him to launch this ball. AJ Brown, look at the location of the football. And then AJ Brown, what amazing athletic dexterity to stay on the sideline. Tiptoe, tight rope, down the sideline. Big 57-yard touchdown. Now the score is knotted at 14-14. And we've got a barn burner in Lucas Oil Stadium. Next play we're going to look at is 126 left in the fourth quarter. This is on Indianapolis eight-yard line. We've got 11 personnel down here. You can see that the Titans now are deployed in a nickel defense because of the 11 personnel. Frank Wright, who is a plate caller for the Indianapolis Colts, dials up a screen trying to get out of the shadow of his own end zone. Very well played by the Titans defense. Tremendous pressure up front. Beautifully diagnosed by Elijah Molden that's over here on the closed side. Look at the pressure. Watch this pressure up front. Watch the pressure that we are going to get. Watch Danico Autry. Watch Big Jeff. And then look at the tremendous effort from Buttoe Pre. Buttoe Pre not only defeats a cut block, gets up off the ground, rolls into the quarterback, distracts the quarterback. The quarterback has to change the ball. Wintz changes the ball from his right hand to his left hand to avoid his safety. Elijah Molden very alertly. Diagnosis to play is right there on the spot. Interception, touchdown. Now the Titans are up 31-24 late in the fourth quarter. Now we're looking at 6-26. We're in overtime. It's first intense scores now 31-31. Very tight ball game. We've got 12 personnel, two tight ends, both off the line of scrimmage. Titans now. This is a zone defense. And watch Kevin Byrd who has been playing tremendous middle of the field free safety for Titans all season long. Watch him diagnose this play. Look at him get the directional delivery key off of Carson Wintz. Carson Wintz starts to aim his shoulder over towards Byrd's right. Byrd breaks perfectly on the football. Goes right to the exact interception point. Cuts in front of the ball. Interception up the sideline to set up Randy Bullock for another game winning field goal. Titans win a thriller in overtime.
