Certain reporters and pundits -- well, mostly Stephen A. Smith -- are very eager to push the controversy over whether Chip Kelly is a racist. They commonly write (or threaten?) that the issue will continue as long as Riley Cooper is on the team. It's cheap drama and easy clickbait, requiring no actual reporting or thought at all.
Of course, this argument ignores the fact that coach Kelly deferred to team leaders (notably Michael Vick and Jason Avant) to decide whether Cooper should stay. Cooper has kept his nose clean since then, and it would make no sense to retroactively punish him just because click-baiting journalists demand that the team does.
