"It definitely feels more like a loss than a win, because we moved the ball so well and had so many opportunities to win," Cousins said.
Washington (4-3-1) appeared to have the game won with 2:13 left in overtime, but Dustin Hopkins hooked his 34-yard field goal attempt wide left.
Hopkins, whose first overtime attempt sailed smoothly through the uprights but was negated by a last-second Bengals timeout, appeared calm and unruffled in the locker room.
"It was slick out there, but that didn't have an effect on any of my kicks," said Hopkins, who also was badly short on a 55-yard attempt at the end of the first half.
"Obviously not winning the game is disappointing," Bengals coach Marvin Lewis said. "We had opportunities on both sides of the ball to win it."
Dalton completed 27 of 42 for 284 yards and a touchdown to Tyler Eifert, who saw his first significant game action following offseason back surgery. Eifert made nine catches for 102 yards, while A.J. Green generated 121 yards on nine catches. Dalton also tossed a costly interception early in the fourth quarter with the Bengals driving deep into Washington territory.
