Team looks pretty good for a salvaged wreck
Ellsbury needs some better company in your OF, as you indicated. I would try to sell high on Matt Joyce (I'm not a believer) and market a closer or two.
While everyone seems to love Scherzer, I think his performance will get rather inconsistent as the season goes on. If you're living on the edge, you might trade him while he's hot and get a strong, young bat in return.
