George Pickens issued an apology... but was it sincere?

George Pickens issued an apology. Was it a real apology? Austin doesn't think it's sincere and wants to see him ball out as one of the most talented receivers the Steelers have had since Antonio Brown. Does Mike Tomlin see wide receiver talent and think he can 'fix' the egos of wide receivers who have a lot to say or not do on the field?
