Bortles, who was 11 of 15 in a preseason opener, hit 8 of 16 passes for 98 yards. His chances for scoring touchdowns were hurt by poor offensive line play at times, a holding penalty in the red zone and a drop.
"Obviously you want six in the red zone instead of three," said Bortles, who completed passes of 20 and 26 yards to spark the first two drives. "We shot ourselves in the foot a couple of times with missed opportunities, but overall the guys did good."
"I don't think we were far off on a number of them," Manning said of Beckham. "We were pretty close on both of them. We'll keep repping things and getting a good look at it."
What's alarming was that the Giants' offense was supposed to be their strength this season. It's now produced a field goal in seven series.
"We've got to get better," Manning said.
Brown converted field goals of 51, 43, 53, 37 and 28 yards. He also missed one, but a Jacksonville penalty kept the drive alive and Harris later scored.
