Following Week 2 actions, SWN has covered some players fantasy owners should be targeting as good value additions. Now, the attention shifts to players whose values are at a high point. Trading these players now is prudent-as the year goes on their performance is likely to regress back, and ruin your chances of getting much in return.

Arian Foster, RB Houston Texans

Foster's been great through two weeks, piling up 241 yards on the ground in just two games to go with a touchdown. He's been a star in the past too, so why the concern?

He entered 2014 with injury concern, and is averaging 28 carries per game. The heavy workload does increase his yardage, and while that'll be good for as long as it lasts, Foster's going to break down at this rate. Head coach Bill O'Brien has stated he plans on giving him less work to maintain his freshness, but with shaky backups that's easier said than done.

Trade him now-he'll probably fetch a ton from an owner hurting with injuries, and be happy when you have productive players while the owner you traded him to sweats out "questionable" Sunday mornings.

Julian Edelman, WR New England Patriots

Edelman's looking like a great buy after two weeks-Tom Brady has targeted him 15 times and he's caught 12 passes at 14.7 yards a pop. That's a much higher yards per catch rate than he's ever posted before though, and he's benefitting from increased targets while TE Rob Gronkowski works his way back to health.

In the long run, Edelman won't be a source of touchdowns, and he will revert to being a more typical slot player running short routes across the middle. Trade him now to a nervous A.J. Green owner-you may get a good haul.

Zac Stacy, RB St. Louis Rams

Things are bad in St. Louis for the offense, and they're going to get worse. Stacy has posted solid numbers through two weeks, so now's the time to jump ship. He's still not hitting the magic four yards per carry mark, and with their abysmal QB situation he's going to be the first, second and third focus of opposing defenses.

Making matters worse, he's just not an option for the Rams in the passing game, so he can be expected to lose third downs to Benny Cunningham on a regular basis. Cut bait now-as the weeks go on, owners will be stuck with a merely decent option who will be largely touchdown dependent.

Delanie Walker, TE Tennessee Titans

This Walker thing is getting carried away. Most owners probably picked him up because Dallas has a porous defense, and they were smart to do so. He rewarded them with a huge game. Now trade him! Walker is a serviceable tight end, but week to week he's going to frustrate owners more than anything. Touchdowns are a fickle beast, and if he's being counted on to approach 14 targets a week, like he got vs. the Cowboys, then good luck with that. I'd see if I could package him with another player, and upgrade somewhere with a two-for-one deal.
