Context: In the team's home opener, former Heisman Trophy winners Johnny Manziel and Marcus Mariota started against each other, and the two combined for over 400 yards with each having a pair of TD's and no INT's. After the Browns led 21-0 at halftime, Anthony Fasano and Dexter McCluster factored in each of the scoring drives for Tennessee, as defensive containment limited Mariota for most of the game. The Titans cut the deficit to 21-14 late in the 4th quarter.  On their next drive, the Browns reached midfield and faced 3rd and 2.  On a broken play, Manziel found Benjamin and threw a touchdown to put the Browns up 28-14.  The Titans reached the red zone on their next drive, but Mariota fumbled and lost the ball, allowing the Browns to run out the clock.  After committing 5 turnovers in their season opener, the Browns had 0 turnovers while forcing 3 Titans turnovers.  For Cleveland, Armonty Bryant led the Browns with 2.5 sacks (of the 7 total) as they pressured the Titans to turn over the ball 3 times, and a selection for AFC Special Teams Player of the Week was bestowed upon WR/KR Travis Benjamin, who had 269 all-purpose yards, including a 78-yard punt return TD. With the win, the Browns ended their six-game losing streak and improved to 1-1 on the season.  Benjamin's 3 TD's were all over 50 yards, becoming only the third player in NFL history to have three 50+ yard touchdowns in the same game.
