Manuel completed five-of-11 passes for 105 yards and the lone touchdown, coming after all three of the quarterbacks had taken turns with the first-, second- and third-team offenses.
Matt Cassel was just two of six for 27 yards. The play-calling concentrated on establishing the run when he was under center with the first-team offense.
Tyrod Taylor showed glimpses of talent, going eight of 13 for 83 yards and another 31 rushing yards. Coach Rex Ryan was disappointed, however, that Taylor missed a few throws.
Although Ryan noted that it's normal for the defense to be ahead of the offense early in camp, he acknowledged he was hoping for a stronger showing from his quarterbacks.
"I was hoping to see something else pop through there, but it didn't," Ryan said.
Yet to impress his new team going back to offseason practices, Cassel is still likely to be afforded veteran deference in the preseason opener.
"We'll probably start Cassel in the first game against Carolina and we'll just go from there," Ryan said. "Obviously we'll rotate guys who get a shot to start."
Here's what else we learned in Saturday's scrimmages:
"You can just see his confidence," coach Gus Bradley said of Bortles. "Obviously, we have a lot to work, but to get out there for the first time in a game situation, I thought there was some good stuff."
"He's going to be a matchup nightmare for a lot of teams," Skuta said after the scrimmage. "Get him on some guys that aren't used to covering him like me. That's what happens with good players. You've got to be perfect."
»Bengals backup A.J. McCarron mirrored Bortles' performance, leading a pair of scoring drives with the first-team offensive line after failing to move the offense on his first two drives.
"I thought he was even better than last night," offensive coordinator Hue Jackson said. "Every time he completed a ball his confidence skyrocketed. It's a good opportunity for him to continue to grow."
» Although Matthew Stafford missed some throws, he threw a pair of touchdown passes to Calvin Johnson and Eric Ebron and led two more drives into scoring territory. Stafford completed nine of 10 passes on the Ebron touchdown drive, connecting with the second-year tight end four times. It's a promising sign that the two are developing strong chemistry after a disappointing 2014 season.
