SANTONIO HOLMES, WR, PITTSBURGH
After stepping into the starting lineup late in the season, Holmes displayed the big-play ability that made him a first-round selection. In four starts, he averaged 20 yards a catch and proved to be a nice complement to receiver Hines Ward. After an offseason spent polishing his route-running, Holmes could become the vertical threat the Steelers have lacked since Plaxico Burress left via free agency.

RICHARD MARSHALL, CB, CAROLINA
As a rookie, Marshall replaced the injured Ken Lucas in the lineup. And after leading the team with seven takeaways, Marshall not only wrestled the starting job away from Lucas, but also established himself as the Panthers' top corner. He's bound to earn Pro Bowl consideration in his second year.

JASON PETERS, OT, BUFFALO
The former college tight end has made a smooth transition to offensive tackle. The Bills recognized as much and rewarded him with a five-year extension in the offseason. Don't be surprised if Peters and new teammate Derrick Dockery are lauded this season as one of the league's top offensive line combos on the left side.

ROBERT GEATHERS, DE, CINCINNATI
Geathers led the Bengals with 10.5 sacks last season, despite playing as a situational pass rusher. A high motor guy with a relentless energy, he is a force off the edge. As the first Bengal player to record double-digit sacks since Alfred Williams in 1992, Geathers has earned more playing time in the Bengals defense. Given more snaps, he could challenge for the league lead in sacks.

ANTHONY SMITH, FS, PITTSBURGH
Despite spending most of his rookie season in a reserve role, Smith has a chance to emerge as an impact playmaker in his second year. His combination of ball skills and awareness makes him the ideal free safety as the Steelers blend in more Tampa Two coverage. With two interceptions and five breakups in four starts last season, Smith has shown that he is capable of being a difference-maker.
