One of the biggest issues the Jets have to solve before they take the field again in two weeks is what’s going on with the offensive line.

The unit was terrible on Sunday and has struggled mightily through the first three weeks.

“We just didn’t play very good as a group,” coach Adam Gase said. “I think there was a few times when we did have some good lanes, we didn’t always hit them. We missed a couple run reads. We didn’t do a very good job as far as there was a couple times where we should’ve got the ball out. There were a couple times where we took some bad sets and where we got kind of beat on some of their twist games.”

Gase said the Patriots did not surprise them with anything. The Jets just did not execute. The Jets allowed five sacks in the game and could not open up any holes in the run game. That led to 105 total yards in the game.

“We knew what kind of game we were in for as far as what they were going to, really, kind of bring at us with what they were going to do up front,” Gase said. “We just didn’t do a very good job matching their speed and we got turned sideways. We had some penalties that got declined. Our techniques and fundamentals just were not there. We just did not do a good job. We did not carry over practice to the game.”

Left tackle Kelvin Beachum was asked why this group of five veterans is struggling so mightily.

“I wish I had an answer for you,” Beachum said. “At the same time, we’ve got to find an answer. The bye week is coming at a good time for us to assess where things are.”

QB Sam Darnold is not the only player the Jets are hoping to have healthy and returning to the lineup against the Eagles in two weeks. Gase said LB C.J. Mosley (groin), DL Quinnen Williams (ankle) and WR Demaryius Thomas (hamstring/knee) are all improving and they have a “good shot” of playing against Philadelphia.

The Jets will not practice during the bye week. The team had meetings on Monday and will have more on Tuesday and then the players are free to leave. Gase said he thinks it is more important to have classroom time and go over things than it is to practice this week. He also said the Jets’ injuries play into the decision.

“That’s just kind of been the way I’ve done it and really, for our guys, we’ve got a lot of guys just coming through these injuries that we want to make sure that these guys get back to as close to 100 percent as possible, so we’re ready to go for the Philly game,” Gase said. “That was just kind of, really, the thought behind all that.”

The Jets signed WR Vyncint Smith off the Texans’ practice squad.
