Wide receiver Mario Manningham will become an unrestricted free agent next month, and it seems unlikely that the four-year veteran will return to the New York Giants for the 2012 season.

The Giants have work to do to get under the NFL salary cap, they won't use the franchise tag on Manningham as that would put their No. 3 receiver's salary at $9.4 million next season, and it is apparent that one of the Giants 2012 Super Bowl heroes will have plenty of options this offseason.

In his 'Monday Morning Quarterback' column this week, SI.com's Peter King wrote that their are six teams that are at least $40 million under the salary cap, and that five of those teams have needs at wide receiver.

Those teams are Tampa Bay ($67 million), Kansas City ($62M), Cincinnati ($60M), Washington ($49M), Denver ($49), Jacksonville ($45M).

Per King, all but Cincinnati have needs at receiver. Also, the Buccaneers recently hired former Giants quarterbacks coach Mike Sullivan as offensive coordinator.
