On the flight home from San Francisco, late Monday night and into early Tuesday morning, Jets HC Robert Saleh got a chance to review the film of his team's 32-19 loss to the 49ers and came away encouraged.

"The whole game, it wasn't for a lack of effort as much as guys trying to do too much," Saleh said. "When you play a team like San Francisco, they've been together eight years, they're very precise in what they do. It's as simple as just doing your job. Do your job and we will be in much better shape going forward."

The Jets' defense struggled to contain the Niners rushing attach in the first half, allowing 108 yards including 74 to RB Jordan Mason, who made his first career start in place of the injured All-Pro RB Christian McCaffrey (calf).

In the second half, the defense allowed 72 yards rushing and only 3.1 yards per carry. Saleh could see the unit making changes in real time, and on film started to see similarities to last year's unit which allowed the 11th fewest yards per carry (4.1) in the NFL.

"In the second half, I felt like we got to fixing the run defense," Saleh said. "They had the one explosive but, but it's going to get fixed. It's definitely going to get fixed. I'm not discouraged in any way. Obviously, they executed a hell of a lot better than we did, and we'll be better for it."

The 49ers' methodical rushing attack helped them control the time of possession, 38:40 to 21:20. On offense, Saleh saw the makings of potent unit despite the limited opportunities.

QB Aaron Rodgers, making his first start since last year's regular-season opener, completed 13-of-27 passes for 167 yards, with a touchdown and an interception. He got the ball out to the Green & White's young stars – RB Breece Hall and WR Garrett Wilson – who combined for 154 scrimmage yards and a rushing touchdown by Hall that came late in the first quarter.

"We only had 49 plays," Saleh said. "If we had that 12-play first drive where we had a chance to go score, and it was a lot of Breece and Garrett, but I think as the game would have opened up with more opportunities, I think it would have given more guys involved."

"I think I speak for everybody, especially on the offensive side of the ball, when I say there's a lot of confidence on that side. I know what it looks like, but I also know what the film looks like, and I know, just from the process of how the game happened, our offense is going to be really good this year."

The Jets new-look offensive line, which added three starters over the offseason, also had a hand in the offense's moments of success. All-Pro LT Tyron Smith, signed from Dallas, and RT Morgan Moses, traded from Baltimore, anchored the edges. Rodgers was only sack once.

"From an offensive line perspective, there's a lot of really good things that happened on tape," Saleh said. "… I thought it was a good first outing in terms for a group that hadn't played together and for the quarterback hadn't played in so long, but there was a lot of encouraging things that I know it's going to be a lot better once we balance out this team."

The plan is to get things balanced in hurry with the team scheduled to play on the road against the Titans on Sunday. Tennessee lost to the Bears, 24-17, in Week 1 despite taking a 17-0 lead.

"We're going to get a lot better from Week 1 to Week 2," Saleh said. "We got a great opportunity this week against Tennessee, on a short week. They were very unfortunate not to come away with a win in their game but they got one of the best O-line coaches in the history of football [Bill Callahan], who's given us fits over the last few years. So, it's going to be a tremendous challenge."
