The move paid off quickly with a score for Washington as Haskins' first NFL drive ended with a Dustin Hopkins field goal to cut the score to 14-3.
The rest of the rookie's afternoon was not as bountiful and closer to dreadful.
Haskins finished 9-of-17 for 197 yards and three interceptions in his debut. All three picks came in the last 17 minutes of play with Washington down by three scores.
As the 0-4 Redskins move forward, Gruden declined to name Haskins the starter for the weeks to come, but made a point that the rookie out of Ohio State wouldn't garner the starting nod due to his draft status.
"You're not handed the keys because of where you're drafted," Gruden said via ESPN. "You have to earn the right."
Heading into Sunday, Keenum really hadn't played all that badly, having completed 86-of-124 passes (69.4 percent) for 933 yards and seven touchdowns. However, he turned the ball over five times in a Monday night loss to the Bears and on Sunday against the Giants was 6-of-11 for 37 yards, an interception and a 23.7 passer rating.
