http://insider.espn.go.com/nfl/blog...12-nfl-draft-playoff-teams-find-interior-help Mississippi State DT Fletcher Cox* Cox has declared for the draft, and there's a lot to like about his versatility. He has the skill set and frame to push for playing time at defensive tackle in a four-man front, or move to defensive end in a three-man front. Cox's greatest strength, though, might be his hands. They are active and violent, which makes it difficult for offensive linemen to sustain as run-blockers or pass-blockers. He will play high at times, and at 296 pounds Cox will need to play with better pad level in the NFL, but because of his versatility and a weak overall defensive tackle class he remains a fringe first-round pick. The San Francisco 49ers pick late in the first and could be in the market for a defensive end in their 3-4 scheme. Cox would immediately bolster their depth and has the tools to become the heir apparent to current 49ers DE Justin Smith. Iowa State OT/OG Kelechi Osemele Osemele played left tackle for the Cyclones and a team could line him up at right tackle in a pinch at the next level, but there's no doubt his best fit is at guard. His footwork is inconsistent and he doesn't have enough lateral quickness to match up with the speed NFL defenses bring off the edge. On the other hand, Osemele has the frame (6-foot-5, 337 pounds), overall strength and nasty disposition to push for immediate playing time at guard. He can be seen on film driving defensive ends into the ground and putting linebackers on their backs. A team like the Cincinnati Bengals would do well to land Osemele if he makes it to their pick in the second round. The Bengals have three free agents at guard, including both starters, and finished in the bottom half of the league in rushing yards per game. Vanderbilt DC Casey Hayward Hayward is an above-average athlete, but he has average top-end speed and lacks the kind of quick-twitch explosiveness NFL teams covet at corner. He also didn't play the ball as well as you might expect from a player who picked off 13 passes over the past two seasons. So how has he been so productive? Hayward's instincts and recognition skills are excellent. He frequently gets an early break on the ball because he reads both the receiver and the quarterback, and he's willing to step up and help out in run support. Chicago should look for help at corner, considering the Bears have three free agents at the position and Charles Tillman turns 31 during the offseason. Hayward is a perfect fit for defensive coordinator Rod Marinelli's zone-heavy scheme, and while it could reach for him in the second round Hayward could very well be available when Chicago makes the first of its two third-round picks. Cincinnati DT Derek Wolfe Wolfe is another versatile defensive lineman who has played the 4-3 tackle spot and at end in a 3-4. He projects as a nose tackle in a four-man front or a defensive end in a three-man front, and the reason is that he's stronger than he is quick. While he's not going to win many battles with his quickness at the NFL level, Wolfe anchors well when teams run at him and also shows the motor and upper-body strength to get to the quarterback on occasion. Wolfe is a fringe second-round value, and New England could do well to take him late in the second. The Patriots have four free-agent defensive linemen, they could stand to get younger along the defensive line and Wolfe's versatility makes him a good fit for that hybrid front.
