Who are the Raiders going to draft next month?

The Raiders just got two solid offensive line men Kalif Barnes and Samson Satele so I dont think the offensive line is a problem no more but the other side is,Tommy Kelly all that money and didn't even prove himself,Derrick Burgess his good but ain't getting any younger also safety josh Horton don't no much about him so I don't know about that situation..Wide receiver I like crabtree but he got hurt so Im pretty scared If we draft him and it doesent work out.So I need to know who you think the Raiders are going to draft realistically remember Al Davis loves speed.
