Aaron Rodgers lamented a number of mental mistakes, missed assignments and poor decisions in the Green Bay Packers' 23-7 loss to the Minnesota Vikings.

Christian Watson dropped what would have been a 75-yard touchdown catch on the Packers' first offensive play of the season.

"Obviously, it'd be great to have a 75-yard touchdown to start the game," Rodgers said. "But drops are going to happen. It's part of the game. It's the mental stuff that we just can't have because we're hurting ourselves. Whether we're going the wrong way on a block or missing a protection something or missing a hot [route] or not running the right route [at] the right depth, there was just too many mental mistakes."

Green Bay's wide receivers had 12 catches for 120 yards, while Davante Adams totaled 10 receptions for 141 yards and a touchdown in his debut with the Las Vegas Raiders.

"Look, we've got to have patience with those guys," said Rodgers, who finished 22-for-34 passing for 195 yards and no touchdowns. "They're young. They haven't been in the fire. The patience will be thinner as the season goes on, but the expectation will be high. We'll keep them accountable, but it's going to happen. There's going to be drops. Hate to see it on the first play, but it's part of it -- there's going to be drops throughout the season."
