Myron Rolle, S
(Signed Feb. 8)
Playbooks aren't the only books Rolle has been studying.
Rolle was named third-team All-American after his junior year at Florida State. However, he also was named a Rhodes Scholar. So instead of entering the NFL draft, he spent a year at Oxford University.
The Tennessee Titans chose him in the sixth round of the 2010 draft, but he never saw the field and was cut before the 2011 season.
Rolle told the Pittsburgh Post-Gazette that his time away from the game made him rusty, and that's part of the reason it didn't work out for him in Tennessee.
There might be room in Pittsburgh for the 25-year-old Rolle. Ryan Clark and Troy Polamalu are entrenched as the starters at safety, but Clark will turn 33 next season and Polamalu is 31. Ryan Mundy, 27, has starting experience and might be hard to beat out.
Beyond that, any spot on the depth chart could be within Rolle's reach. The Steelers didn't draft any safeties, so it remains a position of need.
Hopefully for the Steelers, Rolle's academic accomplishments haven't made him too civilized for the game.
Robert Golden, S-CB
(Signed April 30 as an undrafted free agent)
Golden played both safety and cornerback at Arizona, so he has the "position flexibility" that Steelers coach Mike Tomlin craves.
SI.com hints that Golden might be better suited to the cornerback position because he's better at man-to-man coverage than zone coverage.
Golden has decent ball skills, returning two of his four career interceptions for touchdowns in college.
Walter McFadden, CB
(Signed Jan. 20)
Walter McFadden was teammates with his brother for a few weeks until the Steelers cut Bryant McFadden on Feb. 8
The younger McFadden is no stranger to The Show. He was drafted by the Oakland Raiders and played four games for them in 2010. They cut him before the 2011 season and he joined the Jacksonville Jaguars practice squad.
Walter McFadden made six interceptions at Auburn in 2009, according to ESPN.com.
Terrence Frederick, CB
(Drafted in seventh round)
The Steelers used the third of their four seventh-round draft picks to choose this cornerback from Texas A&M.
The 5'10", 187-pound Frederick is small and slow, according to NFL.com. That seems like a bad combination.
However, he compensates with smarts, using angles in coverage.
The Steelers have a three-way battle for the cornerback spot opposite Ike Taylor. Depending on who wins the starting job, Keenan Lewis, Cortez Allen or Curtis Brown can fill out the nickel and dime packages.
Frederick is likely nothing more than training camp fodder. The reason this grade isn't lower is because you don't expect much from a seventh-round compensatory pick anyway.
Andre Freeman, CB
(Signed May 18)
Freeman is a local kid who played at Penn Hills High School and Division II Slippery Rock.
The Steelers historically have had mixed results with Division II players.
There was Greg Lloyd. Then there was 2004 second-round bust Ricardo Colclough. Isaac Redman is the only player from a Division II program currently on the Steelers' roster, according to the Pittsburgh Post-Gazette.
Freeman made his presence felt at the Steelers' organized team activities. He stayed with fellow Steelers hopeful Marquis Maze in coverage and also made an interception.
Fairy tales don't always come true in the NFL, but Freeman might have a puncher's chance of making his favorite team.
