News that the Pittsburgh Steelers had signed former Ravens cornerback Corey Ivy drew smiles from his former teammates Wednesday. But a few Ravens -- who welcome the Steelers to M&T Bank Stadium on Sunday night -- agreed that Ivy’s value in terms of providing inside information might be a little overstated. "With every team, you’re going to see a foundation under the offense," wide receiver Mark Clayton said. "From that, you have your variations, and we certainly have our variations that don’t allow you to really just key in on our stuff. So I can’t say that it’ll help much." Similarly, cornerback Frank Walker said that Ivy might not have much information regarding the Ravens defense, which has changed since last season. "Everything changes from year to year," Walker said. "We’ve got a completely different defensive coordinator from last year. So you can say what you want, but the reality is that it may be the same concept with different people, but you never know. … To a certain extent, he’s going to tell them what he knows or what he thinks he knows – which any player would do."
