Boldin visited the Bills on Monday, but left team facilities without a deal in place, Vic Carucci of The Buffalo News reports.

This doesn't mean the Bills won't sign him, but it also reveals that Boldin isn't a slam-dunk fit for Buffalo. Perhaps Boldin's contract demands were too hefty for the Bills, or maybe the veteran Boldin has another opportunity or two he wants to first explore. If Boldin does sign with Buffalo, an already difficult-to-read receiver situation beyond No. 1 wideout Sammy Watkins will be adding a few walls to the maze.
