Changes in store for Steelers CB corps?

At age 33, we saw CB Ike Taylor's on-field prowess diminish in 2013 to the point that he was relieved of his long-time duties as the man covering the top opposing receiver. He's due $7 million with a nearly $12 million cap hit in '14, but since none of that money is guaranteed, it's possible that Taylor will be let go. Even if Taylor sticks with the Pittsburgh Steelers next season, we should expect Cortez Allen to handle the opposition's top wideout more often.
