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

So if the coverage responsibilities are less for an OLB in the 3-4, and strength at the POA is more important on the strong side, is it a role that Galette could fill, with Wilson and his speed/athleticism coming off the other edge as the Rush OLB?

If things remain largely the same with our LB corps entering next season (with a draft pick being added that may or may not be ready for extended PT) who on our current team fills the OLB spots THE BEST?
