What are the Niners Nation's thoughts on using one signing Elvis Dumervil? 

I know Right Tackle and Kick Off/Punt Returner are thing of pressing need but I wonder how much better would the D be with a player that has almost 3 times as many sacks as our sack leader.  I like what we have but if we can improve using a draft pick I do not see a problem with getting a proven player rather then a rookie.
