Each week in the NFL season, there will be standout performances by players whom standout performances were not expected. Week 2 was no exception.

The exception is that few, if any, of these players will have the opportunity to maintain that productivity — due to starters returning from injury, good matchups in Week 2, or coaching ignorance. Here’s some guys of note this week who might appear on your waiver wire, and what action to take.

Who to claim

Mark Sanchez, QB, Jets

After his three-TD game in a convincing win over the Patriots, you will hear how he’s turned the corner, how he is becoming the elite QB the Jets sought when they drafted him. But don’t jump the gun. He is just a week or two or four from a four-INT game. There still will be bumps in the road. But if you have Matt Cassel, Vince Young or David Garrard as your backup, you have our permission to pick him up.

Josh Freeman, QB, Buccaneers

Freeman looked great in a Week 2 win over the Panthers, but like Sanchez, more agony is to come. However, we do believe Freeman has a better short-term upside — we could see him throwing for two TDs and running for another more often than we see Sanchez tally three scores. Consider him in the same class as Young/ Garrard, etc., just a tick below Sanchez.

Who to bypass

Mike Tolbert, RB, Chargers

An injury to Ryan Mathews opened the door for Tolbert’s big game. But we think he’ll turn into a one-week wonder. Ryan Mathews is expected back next week, and we don’t see San Diego handing their running game to a fullback instead of their first-round draft pick.

Jason Snelling, RB, Falcons

Starter Michael Turner is expected back in Week 3. If you need a handcuff for Turner, Snelling is your man, with Jerious Norwood out for the season. Beyond that, Snelling’s value is minimal.

Jimmy Clausen, QB, Panthers

Nothing Clausen has shown us, in his limited action thus far, makes us believe he is the answer for Carolina. He hasn’t thrown downfield enough for us to adequately gauge his potential, but we get the feeling this move will not help WR Steve Smith’s value. Make him turn in a good game or two before you pick him up, and that might be a long wait.

Don’t drop

Vince Young, QB, Titans

He still will be the starter. He had a bad game, as he is prone to do. And he was playing a great defense. He will continue to be inconsistent, but he still have better upside than most QBs likely to be used as fantasy backups. Just cross your fingers and hope he has one of his good games when your starter is on a bye.

Michael Vick, QB, Eagles

We’re trying, but the Tracker is finding it hard to conjure a suitable analogy for the idiocy that is going on with the Eagles QB situation. Kevin Kolb has been unproductive (you could argue counterproductive) when under center. The offense has been explosive with Vick running the show. So why bring back an ineffective QB, who recently had a concussion? Sooner or later, sanity must prevail. Unless you don’t have another starting QB option, don’t cut ties with Vick just yet. Let Kolb play his way out of the job over the next week or two.

Who to pick up

Dustin Keller, TE, Jets

When Sanchez has a good day, so will Keller. He is even more valuable over the next two weeks, before WR Santonio Holmes makes his Gang Green debut. Even after that, we think he can be a borderline top-10 TE. Consider him to replace Jermaine Gresham, Todd Heap or Greg Olson.

Marcedes Lewis, TE, Jaguars

We like Lewis even more than Keller. The Jags don’t have as many targets as the Jets have (or will have once Holmes suits up). And Garrard has shown a comfort level with Lewis early in the season.

Peyton Hillis, RB, Browns

If you are thin at RB, Hillis outplayed starter Jerome Harrison again in Week 2. But only use either back as a bye-week or injury fill-in.

Who to drop

Reggie Bush, RB, Saints

He should have been a fourth option at RB for your squad anyway. No he’s out for up to six weeks, and who knows how long before he’s back up to full speed.

Who to trade

Brandon Jacobs, RB, Giants

He is a man-beast who wants to run like Barry Sanders. He is disgruntled, on the outs with coaches, and is not the top backfield option for Big Blue. Shop him if you can, but chances are no one will bite. If there’s someone on the wire you feel strongly about, and dropping Jacobs is the only way to make the transaction, don’t let that stand in your way. But, if you are in a fantasy helmet-tossing league, pick him up right away.

Braylon Edwards, WR, Jets

He had a productive Week 2, but he is not the top-line WR of several years ago. And when Holmes return, Edwards will see even fewer throws his direction.

Steve Smith, WR, Panthers

You can try to sell Clausen as a potential boom to Smith’s numbers, but we don’t believe it. Deal him now while he still has some legitimate value.
