Wes Welker is hoping to receive an official contract offer from the New England Patriots before free agency starts Tuesday. If it happens, it will be the first offer the Patriots have sent Welker during months of negotiations. NFL.com's Ian Rapoport reported that the Patriots haven't extended an official offer to Welker during all of their conversations, according to a source. Teams are wary of getting official offers shopped around at this time of year. It's hard to believe Welker's agents don't know the rough ballpark of where negotiations stand, and whether or not the Patriots are willing to pay enough to keep Welker off the market. Source: NFL.com
