I think Mundy is a solid backup safety for both spots. But do I think he is better than Ryan Clark? No.
Ryan Mundy is kind of the Ramon Foster of the defensive backfield. A guy you like to have for depth. Is able to hold his own when he starts. Underrated by Steeler fans in general. But he isn't a world beater either. I think he's a bridge-type player who could hold the fort for us until we are able to draft Troy and Clark's eventual replacements in the next draft or two.
Well they better draft though eventiual replacements before the bridge falls down because Mundy is very average. Like Foster he needs to be a back-up who is only on the field in an emergency. He is however better than Foster in that he at least plays on Special teams.
Playing Fantasy Football does not qualify you to be the in the front office or on the coaching staff of the Pittsburgh Steelers. They are professionals and you are not!
