Assuming its the points only league in your signature. I think you keep both and drop Bogosian. Bogosian is stuck behind Enstrom and Byfuglien and his short term upside is limited.
If you can only keep one I would go with Green. Kulikov is not doing much better in the injury department and Green has a proven track record when healthy.
12 team, Keep 8 H2H daily start
