The Steelers made a big free agent signing Monday, adding cornerback William Gay at a three-year deal.
It wasn't all that surprising. As soon as Gay was released last week by Arizona, which had signed him to a two-year, $4.95-million contract last season, the natural fit was for Gay to return to Pittsburgh.
It was a move similar to the one made by Bryant McFadden a couple of years ago. Unlike McFadden, however, Gay still has tire left on the tread.
Gay was solid in the slot for the Steelers in 2011 before leaving for Arizona, and that's likely where he'll be asked to play in 2013. That means Cortez Allen will move into the starting lineup on the outside opposite Ike Taylor, though the Steelers will likely call it an open battle between Allen, Gay and Curtis Brown heading to training camp.
It also means that the Steelers will now likely let Keenan Lewis walk - unless he finds the free agent market more soft than anticipated.
The Steelers liked what they saw of Allen last season, particularly when he started in place of Taylor in the last few games. Pittsburgh needs more playmakers in the secondary, and despite Lewis' solid play last season, he just isn't a guy who's going to get a bunch of interceptions.
What the Steelers can do is use the money they might have used to re-sign Lewis to make other moves, ie. sign a running back.
