They do need help, they need CB depth badly and they could use another guard to replace Hutchinson. It's not like they're a perfect team, everyone has holes. They won't waste a first round pick Moss just for KR and PR, they might as well just wait because later on in the draft there will be guys where the only way they can contribute is KR and PR.
I think that they need a safety more then they need a CB. I really think that Ko Simpson is a better chioce then Bing. Simpson is a hard hitter with good tackling ability. He wasn't on the list so I went with Moss another need for the Seahawks. They can get a olineman with their second pick.
