NFL Week 5's worst QB performances: Browns must bench Deshaun Watson

Per Stathead, former Seahawks quarterback Stan Gelbaugh in 1992 was the last quarterback to have a completion percentage of 30% or worse with at least 30 attempts when he finished a 20-17 overtime loss to the Eagles 9-of-31 for 66 yards, one touchdown and two interceptions.

For a season that began with bold claims of Allen being the MVP favorite, being mentioned in the same breath as Gelbaugh, who completed 49.1% of his passes in six NFL seasons, is a steep fall from grace.

Panthers quarterback Andy Dalton

Dalton was as forgettable in Sunday's 36-10 loss to the Bears as he was in his lone season in Chicago. The veteran quarterback, meant to stabilize a dysfunctional offense, only highlighted Carolina's inadequacies in the loss.

He finished the trouncing 18-of-28 for 136 yards and an interception while also losing 20 yards on three sacks before being benched for former starter Bryce Young.

Fortunately for Dalton, his job appears safe. Head coach Dave Canales revealed he only threw Young into the fire because of offensive line injuries. (h/t The Athletic's Joe Person)

That might make Young the world's most expensive punching bag, but it also means Dalton will have the opportunity to produce more stinkers in the coming weeks.

Jets quarterback Aaron Rodgers

In New York's 23-17 loss to Minnesota in London, Rodgers was 29-of-54 for 244 yards, two touchdowns and three interceptions. It was just the sixth three-interception game of Rodgers' career.

"Obviously, that was below my standard," Rodgers said afterward. (h/t Yahoo Sports)

He struggled to read Minnesota's defense and overthrew multiple passes in the loss, New York's second consecutive game in which the offense was disjointed.

Rodgers' performance might be unfamiliar to him, but it's the standard he's set for himself in his brief Jets tenure.

Raiders quarterback Gardner Minshew

The Raiders jumped out to a 10-0 lead on the road against the Broncos in an eventual 34-18 loss.

A poor decision by Minshew swung the game.

In the second quarter, Las Vegas drove to the Denver 5-yard-line up seven, 10-3. Minshew had a chance to extend the lead to 14 but threw a horrible pass intended for rookie tight end Brock Bowers.

Minshew rolled out of the pocket and threw the ball off his back foot, and it sailed over Bowers' head and into the arms of Broncos cornerback Patrick Surtain II, who returned the errant pass 100 yards for a game-altering pick-six.

Denver (3-2) scored the game's next 24 points following the interception to seal the easy win. Raiders head coach Antonio Pierce benched Minshew for backup Aidan O'Connell and wouldn't commit to a starter in Week 7 after the game.

Once he reviews the tape, his decision should be a lot easier.
