The 340-pound Ngata has surprising speed and could develop into one of the most disruptive defensive tackles in the NFL this season. Look for him to shine in a defense filled with stars.

Castillo was limited by an ankle injury in 2006, but still earned second-alternate status for the Pro Bowl. With so much talent on San Diego's defense, offenses will have limited resources to slow Castillo, so the third-year player could easily reach double-digits in sacks.

Hawk has speed and strength and he's a hard worker. With a year of experience, he's poised to have a Pro Bowl-type season.

Wimbley had 11 sacks last year and has the physical tools and savvy to become one of the top pass-rushers in the game for years to come.

Ryans led the NFL with 126 solo tackles and was named Defensive Rookie of the Year in 2006. He's a film nut who has a knack for being in the right place at the right time.

A starter in last year's Pro Bowl, Hall has established himself as a true shutdown corner. He is one of the fastest players in the league and backs up his cocky attitude with production on the field.

Tatupu has already played in a Pro Bowl and is leader on the Seahawks defense. He's a bit undersized (6-foot, 238 pounds), but he makes up for it with his tenacity and intelligence.

The Bears defense fell apart after Harris tore his hamstring tendon in Week 13 last season. But he's back and healthy and ready to be a major disruptive force in the middle. He's remarkably fast for a defensive tackle and very difficult for interior lineman to block.

Merriman was suspended four games for violating the NFL's drug policy and still amassed 17 sacks in 2006. He's fast, strong and his motor is running full speed every time he's on the field.
