Can we bring back Wilson?

Howard, Utley, Martinez.  3 players whom will now (barring a miracle) start the season on the DL.  Replacing them?  Freddy Galvis and.......uh....... Pete Orr?  Hector Luna?  Kevin Frandsen?  (I actually would have been ok with Frandsen, except for the fact that the Phillies are so high on him that they already sent him to minor league camp).  By trading away their top util. player for a reliever that can't even crack the 40 man roster, the Phillies have left themselves in the perilous position of lacking a backup middle infielder.  While Martinez's injury was unexpected, he is far from a great option when healthy.  A serious injury to Rollins and it would have meant Galvis, not Martinez, getting extended play at SS.  The problem now is that with Utley down, Galvis moves to 2nd.  Martinez then becomes the long term SS backup.  So who becomes the short term backup?  What happens now if Rollins gets hurt again?
