NFL Nation previews the 2013 scouting combine by identifying the most important thing for each team to learn about its greatest area of need.
Dallas Cowboys: The switch from a 3-4 defensive alignment to a 4-3, and the likelihood of losing Anthony Spencer to free agency, means the Cowboys' greatest need is on the defensive line. Is there a pass-rushing defensive end who will be available with the No. 18 overall pick? Is there a 1-technique nose tackle they could take in the first or second round who would allow them flexibility with other players on that line? Dallas also needs help on the offensive line and will be looking at the top guards. They traded up last year to get cornerback Morris Claiborne. Could they trade up for someone like Alabama guard Chance Warmack?
New York Giants: It's a good year for the Giants to employ their best-player-available philosophy with their No. 19 overall pick, because they have a number of positions of need. Osi Umenyiora has one foot out the door, and you know the Giants like to look at pass-rushers in the first round. But they could also go offensive line, linebacker, cornerback ... any number of ways, really. For the Giants, the combine will be about prioritizing their needs. Perhaps the interview process helps them figure out which player -- rather than which position -- is worthy of their first-round pick.
Philadelphia Eagles: Drafting No. 4 overall, the Eagles need a franchise difference-maker. Their first order of business is finding out whether their quarterback of the future is in this draft. But if guys like Geno Smith and Matt Barkley don't rise to fourth-pick worthiness, the Eagles will need a building-block piece at a vital position. Luke Joeckel at offensive tackle. Star Lotulelei for defensive line. Dee Milliner at cornerback. The Eagles will be able to pick almost anyone they want and probably get a great player as a consolation prize for their terrible season. Though their greatest roster needs right now appear to be on defense, they shouldn't shy away from using that fourth overall pick on a difference-making tackle or even a quarterback if they find one they love. Drafting in the top five isn't about filling an immediate need as much as it's about finding someone around whom you can build for the long term.
Washington Redskins: The Redskins traded their first-round pick in the Robert Griffin III deal and don't pick until No. 51 -- the 19th pick in the second round. This makes their scouting more challenging and their combine itinerary different from that of many other teams. There's no way for them to guess how the first 50 picks will go, so they must cast a wide net as they look for help at safety and cornerback. Fortunately for them, this draft appears deep with talented secondary players. The Redskins' mission this week will be to try to figure out which of the guys they like will still be available for them when it's finally their turn to pick.
