Rookie minicamp wraps up today and there’s reason to have strong optimism about first-round pick Darrelle Revis and second-rounder David Harris’ potential for contributing to the Jets in 2007.

OK, maybe that’s a leap of faith based on how little we actually got to see them in drills this weekend. But both, particularly Revis, looked like they knew what they were doing on the field. And Harris, at 6-foot-2, 243 pounds, at least looks the part of a strong inside linebacker.

Next up for them, as well as sixth- and seventh-round picks OL Jacob Bender and WR Chansi Stuckey, as well as the undrafted free agents and any of the tryout players the Jets may sign is to join the team for its offseason workout program.

That will allow Harris to mingle with inside linebacker Jonathan Vilma. Surely, he’ll try to pick the veteran’s brain. But Harris said he hasn’t thought ahead to the June minicamp, when he’ll be able to take the field with the Jets veterans.

The important thing is for the rookies to learn the playbook. And that means learning the terminology.

“It’s been pretty good, I’m just like any other rookie, I’ll make a couple of mistakes,’’ Harris said. “We’re trying to pick up everything as quick as possible, it’s great challenge.’’

“Some of the terminology is the same as college and some of it is the same but it’s different wording,’’ said Revis, who played at Pittsburgh for former NFL coach Dave Wannstedt. “Right now, I just have to get focused on the Jets terminology and leave the other stuff behind.’’

Neither Harris nor Revis said there was a moment in minicamp that stood out for them, where they proved something to the coaches. Actually, as much as the coaching staff is looking at the on-field performance, Eric Mangini said he was curious to see how much the rookies could retain the next day from their classroom sessions. The players study then are sent back to their hotel rooms to study their notes and playbooks. The next day, there are often quizzes – quickie quizzes.

“If you do not know anything, then the coach is not going to put you on the field,’’ Revis said. “It’s more of a self thing, to motivate yourself to learn the playbook as well as don’t let your teammates down. It’s all about trust.’’

“In the first couple of days of minicamp, you have to get the playbook and learn what you are supposed to do,’’ Harris said. “Once you do that, you are able to play faster – without hesitation on the field.’’

Indeed, if there is something the rookies need to learn fast is to perform at which Mangini demands. NFL practices – Mangini’s practices – are not for slackers. It’s a completely different intensity level than what the players were used to in college. No mistakes are tolerated.

“Everything’s been up-temp, there’s not a lot of time sitting around and not doing anything,’’ Harris said. “Everything’s moving. There’s constant motion. We’re just trying to impress the coaches and competing and earn a spot.’’

Revis and Harris were roommates for the rookie minicamp, and likely will be for a little longer until they find their own places. Warranted or not, the two are considered the leaders of the rookie class.

Harris said that’s something that needs to be earned on the field.

“I really don’t know,’’ Revis said. “I haven’t talked to any of the players like that. They haven’t told me anything about being a leader.’’

Still, Revis exudes natural leadership ability and confidence. No doubt he will grow into one of the Jets’ team leaders, possibly by his second season.

Mangini was certainly complimentary about Revis and Harris so far.

On Revis: “Some of the edge speed that he showed in the kickoff return drill that we did and even the tackling drills, some of those players that he’s made, you can see the change of direction and then the burst. The other thing that you notice is he’s got a very physical way about him in terms of how he places his hands on people, which is always positive.’’

On Harris: “He’s showing some things in those tackling drills and those punt return drills and even as he’s getting a better feel for how the runs are – how they hit, how the blocking schemes works, you can see some of the positive traits that he showed in college. It’s not just his raw ability, but seeing that ability translate into understanding, how the run is going to hit, how it’s blocked and that overall ability put into the context of an actual drill or a play.’’

Of course, Mangini was quick to remind that what goes on in rookie minicamp, or even in the June minicamp or offseason workouts is not always a definite indicator of in-season performance. As an example, Mangini cited running back Leon Washington, who, if you recall, couldn’t stop fumbling the ball, even into training camp.

Washington wasn’t too bad during the season as a rookie and is now looked at as giving the Jets a good change of pace to Thomas Jones.

In a similar vein, the improvement shown during rookie minicamp is not necessarily the same as what Mangini looks for during training camp or the season.

“We had three guys fall over the bags (Saturday), nobody fell over them (Sunday),’’ Mangini said. “That’s improvement. It’s all of the little things that are getting better daily which then feeds into the big picture.’’

Which, judging as ever so slightly as can be done in rookie minicamp, Revis and Harris should be a part of.
