Looking at Fansgraph team data:
Worst fielders, Cutch, Hoskins, Miller, Harper, Herrera, Janikowsi (working off Def value)
Realmoto was top level, Torreyes, Didi were positive.
Bohm actually wasn't much of a fielding liability, but his hitting was below replacement level.
So if Didi's elbow is better you could live with Bohm - Didi - Segura to start the season, Torreyes on the bench.
Bring in a veteran backup catcher, RH LF and CF?
Biggest problems are 1B, LF and CF, need a CF who's at least average, and a LF who isn't a black hole defensively, if there's no DH guess you live with Hoskins for now. Maybe Kingery in CF?
Marchan - Maton - Williams - Stott - Haseley - Moniak - Randloph in AAA, Muzzotti and Ortiz at Reading to start the season. Let them work their way back to Philly.
