Here is a bunch of quotes from difference sources that I have compiled about Ryan Clark from Steeler fans. What do they all have in common? They all talk about how he has lacking coverage skills, (aka Wilson #2). Do we really want another safety that's a liability in coverage?
"I’ve been a Ryan Clark fan because he lays people out and is a great character guy.
However, at 30 and aging…..his coverage skills are weak and Troy covered them up. And he doesn’t have ball hawking skills! He focuses on the hit rather than the ball. Not worth the money he wants. Go get a free agent on the cheap or draft one in the first round"

"I doubt it was the combine, it was probably falling before that. A lot of people see him as Roy Williams part II.
He just has no coverage skills, his best bet would be either as a MLB in a pure cover 2, and who runs that anymore, or as a big safety in a team committed to running a 3-3-5 on more than just five and long, which is like no NFL team. At this point he just doesn’t look like he’s going to play every down in any scheme. And why would you use a top pick on a player who’s not going to play every down."

"Yes, he can hit, and I've always liked him.
Coverage-wise, I agree with jiminator that Ike Taylor had a worse season than Clark, but it wasn't Clark's best year either. Polamalu's absence spotlighted a lot of holes in the defensive backfield. The problem is that Clark is asking for superstar money and he's not a superstar. Even coming off his best season, he wants more than he's worth--and he's not coming off his best season It's a matter of cost v. benefit; there's no real benefit to keeping him at that price."

Now before you get too excited about us signing Clark realize that he has the potential to be a liability in coverage. Now he is an upgrade over what we currently have but he is not the final solution. This defense was one of the worst in pass coverage last year and we thus need players who can cover the pass, thats most important. Remember how the Steeler's defense played when Troy went down last year? They were not nearly as good and that shows how must their secondary relies on him. Clark is good, but he is not a permanent solution unless he gets better in coverage!
