NASHVILLE, Tenn. -- Depth issues helped kill the 2015 Tennessee Titans.
Quarterback Marcus Mariota missed four games with two knee injuries, and Tennessee lost all four games started by since-departed Zach Mettenberger
Starting outside linebacker Derrick Morgan missed six games and wasn’t himself in a few others before he landed on IR with a shoulder injury. Receiver Kendall Wright also missed six games. Cornerback Jason McCourty played in only four games because he twice needed surgery to repair a sports hernia. Staring center Brian Schwenke only played in the first six games before an ugly injury sent him to IR.
