It's going to be Vaughn as the everyday RF as long as it clicks vs RH pitchers (as should be expected).
Engel will go to RF in late innings and Leury to LF.
Sheets will get the bulk of the starts at DH and sit vs LH pitchers, allowing Grandal to get off his knees and play 1B while Abreu going to DH.
It's really not the end of the world as many see it.
With that said, I really wish they would have done something a bit more grand at 2B.
