Considering they got a #1 pick back from Seattle for Branch, I think they can do well this offseason as far as putting together a good offensive unit.
As for the rest of this year, though, they may have some problems.
Of the WRs looking to move, all have moved at least once. Stallworth's in Philly, Leile's in Atlanta, Walker's in Denver...
Unless they start looking for guys who were cut from other teams or look to trade with teams who are completely out of the race this year (see Tampa Bay, Detroit, Houston, etc.), they're pretty screwed.
