The future isn't so bleak for the Giants offense.
OL - Keep Pugh, Fluker, Jones. They'll need to bring in two new starters, at the tackle position. Highest priority FA and draft picks, plus depth.
TE - Should be fine with Engram and Ellison.
RB - Gallman and Darkwa should be a decent combo, especially if we improve the OL. This would be the lowest of my off-season priorities.
WR - Retain ODB, obviously. Not sure about Marshall's future, so we may need to bring in another WR, at least for depth. We're razor thin behind ODB and Shepherd, presuming Marshall isn't around. Roger Lewis and King are 4th WR's at best.
