Rex Ryan is doing everything he can to make sure the Jets aren’t feeling too good about their 2-0 start.

Ryan today criticized his players for a lackluster practice, saying he “wasn’t happy’’ with what he saw.

“I was glad we never played today,’’ Ryan said. “I think we’ve got to ratchet some things up on defense in particular. I know and I trust that the guys will.

“We had a few too many mistakes out there for my liking. So, we’re going to get that fixed and the guys understand that. We’ve got to make sure that we’ve got it all tight because this is an outstanding opponent and we don’t need to be beating ourselves.’’

When you’re 2-0 and feeling good about yourselves you can afford to nitpick.

Despite the fact that they’re ranked No. 7 overall in the NFL in rushing defense, the Jets aren’t happy with their “ground and pound’’ rushing attack.

The Jets have rushed for 307 yards and a 4.2-yard average in two games, but there ground attack has been inconsistent at times, sputtering early in both the Houston and New England game before breaking some runs.

On Monday Ryan delivered some mild criticism of the offensive line, saying they knew they hadn’t played their best game against the Patriots.

“Rex told us (the offensive line) is the strength of the team, so the bar is set high,’’ Jets RT Damien Woody said. “He was like, ‘This is where I expect to you guys to be at; it wasn’t like he was talking down on us. It was what the expectations. We plan on playing a heck of a football game against Tennessee.’’

That’ll be a challenge considering the Titans’ defense is ranked No. 1 against the run, having allowed a paltry 99 yards on 52 carries for a 1.9-yard average.

“They always seem to have one more person than you have to block,’’ Woody said.

“We fell a little short last week and guys realized that,’’ Jets C Nick Mangold said. “The guys know what needs to be fixed and how to fix those things that caused us to sputter in the first half. I think our offensive line is one of the best in the league. Our guys know how to do the job that needs to be done.’’

The Jets’ rushing attack is two-headed with Thomas Jones having run for 161 yards and a 4.7-yard average and Leon Washington having run for 118 yards and a 4.1-yard average.

“I look forward to us having one heck of a performance this week,’’ Woody said.

Asked if he had any bold predictions like the defense had last week before the New England game, Woody said, “I know, everybody is chattering. That’s (the defense’s) personality. We’re kind of like the quiet storm.’’

Neither Jets CB Lito Sheppard (right quadriceps) nor CB Donald Strickland (right ankle) practiced at all today and both are questionable for Sunday’s game against the Titans. Sheppard said yesterday his injury was feeling better, but he was “day to day.’’

Sheppard has a chance of playing while Strickland will definitely not. If neither can play, Dwight Lowery will start for Sheppard and Drew Coleman will play nickel for Strickland. If Sheppard plays and Strickland is out, Lowery will play nickel.

Other than the corners, Ryan, seemingly mocking the NFL for the huge fine it levied on the Jets last week for not putting Brett Favre on the injury report last season, listed half the Jets roster yesterday.

None of the following is considered serious enough to keep the players from playing Sunday. One of them was Mark Sanchez, who Ryan said “had a little tendinitis’’ in his right knee.

Sanchez participated fully in practice, but Ryan said, “We just added him (to the list).’’

“Make sure he’s on that list … I don’t mean anything by that,’’ Ryan said, drawing some laughter. “It’s just a little thing so we’re going to put him on there.’’

Other players included OL Matt Slauson (ankle), QB Kellen Clemens (right elbow), NY Kris Jenkins (back), S Jim Leonhard (knee), Lowery (ankle), C Nick Mangold (“toes and disposition,’’ Ryan joked.), DT Sione Pouha (ankle), LB Bryan Thomas (ankle), LB Jamaal Westerman (quadriceps), WR Wallace Wright (hamstring), RT Damien Woody (shoulder).

Asked further about Sanchez, Ryan said, “It’s just like a little tendinitis. It’s not that big of a deal, but he has something. I don’t know how to describe it (other than) just to say it’s a little tendinitis, but he’s fine. He fully participated (and) moved around great. We’re making sure we’re looking after him.’’
