CORTLAND, N.Y. -- A few hot topics from Wednesday at the New York Jets' training camp:

• You can't have too many pass rushers: The Jets made a smart move, signing the well-traveled Jason Babin to a two-year contract -- assuming the money isn't ridiculous. Obviously, the 34-year-old Babin is on the downside of his career, but he led the Jacksonville Jaguars in two important categories last season -- sacks (7.5) and snaps among the defensive linemen (772). One of the Jets' goals this summer was to identify another edge rusher to add to Calvin Pace, Quinton Coples, etc. If healthy, Antwan Barnes would be that guy, but he's not close to returning from last year's knee surgery. Rex Ryan, explaining the importance of pass-rushing depth, mentioned two recent Super Bowl champions, the Seattle Seahawks and New York Giants. Yep, it's a copycat league. That the Jaguars cut Babin three months after giving him a $500,000 signing bonus is a bit curious, but that's hardly a concern for the Jets.

• CJ2K is back: The most important development of the day, though not surprising, was Chris Johnson's proclamation that he's been cleared by Dr. James Andrews to participate in training camp. He spent the last month training in Orlando and showed up Wednesday in terrific shape, "flying" in the conditioning run, according to Ryan. I've said this before, and I'll say it again: Of all the new additions on offense, Johnson is the one with the potential to make the greatest impact. When healthy, he's one of the fastest running backs in the league, and the Jets need speed in the backfield.

• Where have you gone, Joe McKnight? Apparently, there are no McKnights on this season's roster. You might recall that McKnight started to play his way off the team last summer by flunking the mandatory conditioning run. This year, no one failed the test, according to Ryan. That, he said, never happened before in his head-coaching tenure. Presumably, this means the Jets reported to camp in tip-top shape. Barnes and guard Willie Colon (knee) passed the conditioning test, yet they still landed on the physically-unable-to-perform list. Don't worry about Colon; he's not that far away from being activated. Barnes? That could take some time.

• The anti-Revis: Not that there was any doubt, but defensive end Muhammad Wilkerson did, in fact, report to camp, backing up previous statements in which he vowed not to stage a contract holdout. He said he never considered a holdout for a second, claiming he wouldn't be acting like a team leader if he pulled a no-show. Truth be told, he doesn't have much leverage to get a new contract, considering he's signed through 2015 and the daily fine would've been $30,000. But give him credit for taking the high road, trying to be a team player -- something Darrelle Revis never did in the past. Now we'll see if Wilkerson's anti-Revis approach has any sway with the powers-that-be.
