ORLANDO, Fla. -- The Buffalo Bills signed Corey Graham for his versatility.
We didn't know how much versatility they saw.
Graham has been a Pro Bowl special-teams player, a respected slot cornerback and good enough to start at regular cornerback for the Baltimore Ravens in the Super Bowl.
We were aware of all that.
This morning, Bills coach Doug Marrone revealed the Turner-Carroll grad is a possible replacement for Jairus Byrd at free safety.
"What's interesting about him is that he can play an outside corner and play it well," Marrone said at the annual NFL owners meetings. "We have two good corners coming back. He can play nickel and start at nickel, and that would be a good competition in there.
"He's also a physical player who had about 70 tackles and four [interceptions]. ... He may be in the mix back there at the safety spot."
Stephon Gilmore and Leodis McKelvin are the cornerback incumbents. Gilmore, coming off a season hampered by a broken wrist, is Buffalo's best. McKelvin had the most effective year of his career. Undrafted rookie Nickell Robey was a revelation in the slot.
Marrone said he didn't know if Graham ever has played safety, but the coach can imagine him in that role.
"There are a lot of things that we've been talking about with Corey and with ourselves as far as the defensive staff," Marrone said.
"We'll go out there in the OTAs, and it'll be the same thing. I like to -- and I always have -- move some guys around a little bit. That's the time where you do it. As you get closer to the season, you don't want to be doing that stuff."
Marrone noted the Bills will need two slot cornerbacks because dime defenses are becoming more necessary in today's pass-happy NFL.
"You need six guys that can cover man-to-man," Marrone said. "And then the other factor is injuries occur in this league. Very rarely are you going to get by.
"You saw what happened to us last year with Stephon being out for so many games. It's a physical game.
"You can never have enough good players, and Corey Graham is a heck of a player."
