"We gotta watch the tape, but we suck," he told Aditi Kinkhabwala of NFL.com.
Cleveland held a 21-7 lead at one point in the third quarter. That came after an interception return by cornerback Justin Gilbert, giving the Browns their second defensive touchdown of the game. In total, the Browns forced four turnovers and held Andrew Luck -- the NFL's passing yardage leader -- to a 24-of-53, 294-yard day.
While the defense was productive, Cleveland's offense managed 248 yards and quarterback Brian Hoyer -- who received his 13th start of the season over Johnny Manziel -- went 14-of-31 for 140 yards and two interceptions. Cameron led the Browns with four receptions for 41 yards.
Cleveland led 21-19 with 10 minutes remaining when Luck threw his second interception of the day to Browns defensive back Jim Leonhard. The Browns could've stretched their lead to nine points, but Hoyer was unable guide the offense to a first down, and Cleveland settled for a field goal.
After the game, Leonhard declined to express frustration with the offense.
"Please don't try to split this team into offense and defense, it's not about that," Leonhard told reporters.
The Browns fell to 7-6 with the loss and are last in a competitive AFC North. The Browns are one of five teams trailing the San Diego Chargers by one game for the final playoff spot.
