What makes a good SAM OLB in the 3-4?

I know you have one OLB in the 3-4 that is primarily a pass-rush specialist (ie. Pat Swilling or Aldon Smith), but the guy on the other side is the one I'm not too sure about. It sounds like you need a guy that is strong enough to set the edge and play the run, but is also athletic and fast enough to play coverage (while also being a capable pass-rusher in his own right). That sounds like a lot to ask in one player. What exactly makes a good strong side 3-4 OLB? ...and is it possible that guy is already on our team in Galette or Martez Wilson? Galette appears a nice fit for the Rush OLB, but would Wilson fit at the other OLB spot?

I think Wilson fits perfectly. His biggest weakness would be the lack of strength to set the edge on rushing plays but what he lacks in strength he makes up for in speed. He would be able to close on outside running plays, blow up boots and screens. Plus he should really excel as a pass rusher. As a 43 OLB his biggest weakness was pass coverage but a 34 OLB has a much smaller pass coverage role that usually consists of covering the flat or shallow zones. In other words he isn't good in pass coverage as a 43 OLB but would actually be very good as a 34 SOLB.
