McGinn says Cobb is already playing exclusively in slot. And he still isn't cutting it.

Not once did Cobb line up outside. All day long he had the slot two-way go against the Lions' fifth and sixth nickel backs, Danny Gorrer and Mohammed Seisay. A hard grader would give Cobb two drops. More alarming was the fact he couldn't beat these newly arrived free agents like a drum. Playing slot in this offense with this quarterback should be a ticket to enormous production and the stardom that goes with that. But Cobb's ho-hum play throughout training camp has carried over into the regular season.
