NFL: AB gives stars new weapon — and makes owners nervous

FILE- In this Jan. 3, 2016, file photo, Pittsburgh Steelers wide receiver Antonio Brown (84) reacts after a first down catch during the first half of an NFL football game against the Cleveland Browns, in Cleveland. Brown has caught a lot of criticism for orchestrating his departure from Pittsburgh, and landing a hefty pay raise as part of the deal. Maybe, if the contracts were fully guaranteed, stars such as Brown wouldn't have to go to such lengths to make sure they're compensated fairly. (AP Photo/David Richard, File)

Some of Antonio Brown’s antics are impossible to defend.
