Philadelphia at Dallas

It seems that, every time the Eagles travel to Dallas, they are destined to shake up the fantasy world somehow.

Well, at least this week, the gaffe in question didn't happen during the fantasy playoffs. No one will ever forget Brian Westbrook's infamous "kneel at the one yard line" last December during the thick of the fantasy postseason. In Week 2 of 2008, Philadelphia rookie WR DeSean Jackson committed a pure mental error that far outdistances Westbrook's kneel for sheer befuddlement. Nothing personal against Jackson, but at least Westbrook's "take a seat" act was strategic, not ludicrous.

Jackson scored what appeared to be a 61-yard touchdown in the second quarter Monday night, but his score was nullified. After further review, the officials found that he had the audacity to flip the ball behind him in celebration ... just before crossing the goal line. If you started Jackson last night and lost by say, five points, you are one angry fantasy owner this morning. Jackson's total of 110 receiving yards may be nearly forgotten in light of his "rookie mistake."

Then, as if the fantasy football gods (who could they be, I know I'm not one of them) decided to attempt to somehow make things right in the universe, Westbrook himself then charged in for one of his three touchdowns. If you own Westbrook in a keeper league, maybe you felt just a slight tinge of redemption last night. If you own Westbrook in any league, you're very happy that Jackson is so darn cocky and has a lot to learn, despite all his apparent pure talent.

I would have expected such a riotous act from Terrell Owens, who was on the other sideline, but I'm sure even he got a chuckle out of it afterwards. Despite all the hoopla he will stir this week, though, Jackson's second 100-yard game to begin his career has marked him as an instant fantasy standout. When he had a promising preseason, we were intrigued, but not convinced. When he torched the St. Louis "Lambs" defense in the opener, many of us simply chalked it up to the matchup. Last night, though, Jackson burned a secondary that will prove to ultimately be much better than that of St. Louis, and Jackson is indeed "for real." Well, he is for as long as Donovan McNabb stays healthy.

McNabb was missing his "top two" WRs again last night, yet he didn't hesitate to rifle the ball downfield when he had the opportunities. Jackson was a prime target again, and I can't imagine his role decreasing much in the near future. While he may be the thinnest Eagle to suit up since Todd Pinkston (6-3, 180 lbs.), he's more than just a guy who can get open deep. Jackson isn't afraid to make possession grabs, and he's going to progressively emerge as a quality all-around target this season. If you get any trade offers for Jackson this week (and you will get a few if you own him), turn them down.

McNabb threw only one touchdown pass, yet his fantasy owners should be encouraged by this performance. He spread the ball around well despite a "depleted" receiving crew and made some fine decisions when pressured. McNabb also showed a willingness to scramble and to expose himself to big hits. He survived, and more good performances are ahead. Just in case, though, you should always have that solid backup available.

There was really nothing surprising on the Dallas side of the ball, as Marion Barber III eventually finished with quality numbers again, even though the Eagles limited him early. Yet being a good fantasy owner isn't just about reviewing the obvious from any game and putting in your waiver claims. You also have to look further ahead and envision who can be the next fantasy standout.

Unless you had the Dallas defense/special teams last night, Felix Jones' 98-yard kickoff return for a score in the first quarter didn't mean much, initially. Yet savvy fantasy owners will see it as a sign of things to come. Jones may have more pure upside than any other No. 2 running back in the league right now. His explosive highlight was a clear signal that you should trade for him, especially if you own Barber.

Barber is widely admired for his punishing running style, yet it also exposes him to possible injuries. He is more physical than most runners, and that also makes him more of a concern than the average RB. If Jones ever gets a chance to start this year, he'll deliver an amazing performance or two, because he's that good.

The Cowboys' braintrust has already fallen in love with Jones, despite Barber's obvious value to the team. Jones was the center of attention every time he touched the ball in training camp. Not only can he outrace defenders as we saw last night, but he also has excellent vision, displays nifty cutback moves, and can make defenders look foolish in short space. All he needs is regular carries to get into a rhythm, and Jones is capable of posting outstanding numbers. Once Jones gets his chance to shine, the Cowboys staff will simply have to get him more carries. Dallas will ultimately have two running backs who can excite fantasy owners, even though Barber's outstanding short yardage prowess will no doubt sting those who elect to start Jones in the future.

Still, Jones reminds me of what I saw in Shaun Alexander early in his career. He sat behind Ricky Watters, yet every time he touched the ball, you could see he was destined for stardom. When he finally got his chance to seize the spotlight, Alexander became a fantasy superstar. Most people seem to have forgotten that in light of his recent decline, but Alexander was a fine player for a long time. Jones will soon sparkle, although the presence of Barber will hold him down statistically at times.

Both the Cowboys and Eagles face stiff tests again in Week 3 as they recover from the Monday night shootout. The Cowboys take on the surprising Packers, and you shouldn't see any major letdown from the Dallas offense. The Green Bay linebackers are indeed formidable, but they won't deter Barber. The Packers cornerbacks have difficulty with big, physical pass-catchers, so Owens is due for another big game. That means another fine outing for Tony Romo, who threw three TD passes on Monday and can now be regarded as the premier QB in fantasy. Tom Brady's injury and health issues regarding the supporting casts in Indianapolis and New Orleans keep Peyton Manning and Drew Brees off the top of the list for now.

Still, we have to wonder when Patrick Crayton (two catches for 23 yards vs. Philly) will start living up to increased expectations. I don't foresee an outstanding performance from him against the Packers, who should be able to effectively shadow him while Owens and Jason Witten get the bulk of Romo's prolific tosses. Meanwhile, the Eagles will host the "Battle of Pennsylvania" as they take on the Steelers. Despite Pittsburgh's rep as a stalwart defensive team against the run, no one should be benching Westbrook, who will do his best work in open space as a pass-catcher.

McNabb won't post great numbers, as the Steelers should do a better job of containing the passing game than Dallas did overall on Monday. Yet McNabb is also doing an obviously fine job of valuing the football, so he won't hurt you if you don't have a clearly better option on your roster. It will be yet another firm test for Jackson, as the Pittsburgh defense is sure to give him more respect than the average rookie. The defensive backs will certainly try to jam him and push him around. It's not the best-looking matchup for Jackson, but there is no real way you can justify reserving him at this point.

Until then, owners of top Eagles players can be thankful there will be no more regular season trips to Texas Stadium. Maybe the new home of the Cowboys won't be haunted by unusual fantasy hijinks -- Scott Engel

New England at New York Jets

Matt Cassel completed 16-of-23 passes for 165 yards and did a nice job of managing the offense, but his fantasy value is very limited. Wes Welker was the recipient of numerous Cassel screen passes and remains especially valuable in point-per-reception leagues, but Cassel's unwillingness to take risks down the field severely hinders Randy Moss, who finished the game with just two catches for 22 yards. The Patriots' backfield is turning into an absolute nightmare for fantasy owners. With Laurence Maroney sidelined for two quarters with a shoulder injury and Sammy Morris ineffective (eight carries for zero yards), New England turned to LaMont Jordan, and he responded by gaining 62 yards on 11 carries. None of the four Patriots running backs are worth starting (Kevin Faulk had 66 total yards as well), and if you own Maroney you should look to pawn him off on someone else if you can.
