(Renton, WA)  --  Seahawks cornerback Richard Sherman, whose knee injury went unreported by head coach Pete Carroll in the second half of the season, says the NFL is being too hard on the team for no reason.  ESPN reported last week that the Hawks' failure to report the injury could lead to the loss of a second-round draft pick.  Sherman says football is a violent game and everyone who plays it gets nicked up.  The "Seattle Times" reports there's no timetable for a decision on the NFL's investigation into the Sherman injury and whether Seattle should have disclosed it.
