Loser: Coaching staff
This was a bad game to lose. You had a home field advantage and theoretically the weather should have helped you since the Titans roster is deeper and the team has experienced the heat.
Not only that, but the Titans had the jersey retirement of Eddie George and Steve McNair at halftime and had momentum after taking the lead in the 3rd quarter.
However, an uncharacteristically timid game from Mike Vrabel led to punts and field goal tries instead of pushing the envelope.
Offensively, the Titans failed to attack the up field pass rush of the Colts with screen passes and Delanie Walker felt like a big play waiting to happen every time he was targeted, which wasn’t enough.
Also, there was a formation the Titans used (2TEs to the left, Henry offset to the right) where Mariota would run read option and play action passes and Tennessee brutalized the Colts with that formation for an entire series on their last touchdown of the game. Instead of continuing to attack that, they moved away from it and it may have cost them the game.
Defensively the only thing I would say is that the technique was poor on the pass rush and players were just running into Jacoby Brissett and bouncing off. That combined with the lack of a pass rush and continued screw ups on the edge with contain, hurt what was an otherwise spectacular day by the defense.
This coaching staff has preached “Good to Great” but right now they are just “good”.
