I think without LaRoche and Jackson, Garcia becoming the number 5, Morse or Moore at 1B/LF and slight improvements from Espinosa, Ramos, Strasburg and Harper with a sprinkle of degradation from Zimm, Morse, Werth, Gio and Desmond would warrant around 92-93 wins. JZimm and Ross probably have similar marks.
It's enough to make the postseason, but it might not be enough to win the division outright. I'm less willing to go long term on a position player and would rather have a rental guy for a year or two to play the outfield and have a lefty bat. Spend on pitching.
