Probably not. But there are many members to the Steelers DB's. Cortez & troy have both shown a nose for the ball, as has (surprisingly) Will Gay.
Ike is what he is- an aged vet who is on the downside of his career. Is he overpaid? Yeah, probably. But he isn't the 'problem'. He's still a valuable player, just that the Steelers have committed too much to him for late career production. Chadman suspects he'll be a candidate for release or pay restructure soon. Next year? Maybe, maybe not. But soon.
Unless you have steady turnover of personnel every season, every team will have 1 or 2 vets that are overpaid as a result of age/decline not matching increased wages.
To be fair, Ryan Clark's $5m is more overpriced than Ike's $10m as far as play on the field goes, in Chadman's opinion.
