NFLPA: League trying to bully, shame Harrison with PED investigation

Pittsburgh Steelers linebacker James Harrison has reportedly agreed to cooperate with the NFL's investigation of an Al Jazeera report claiming he used PEDs, but he's not happy about it.

Harrison, via NFLPA associate general counsel Heather McPhee, sent a letter to the league office accusing the NFL of trying to publicly shame and bully the veteran player.

Your most recent letter, distributed to the media before providing it to Mr. Harrison and the NFLPA, confirmed our understanding that, rather than act with the integrity, respect, and thoughtful diligence that an employer such as the NFL should, the League has instead decided to ignore its collective-bargained agreements and try to bully and publicly "shame" a veteran player-employee who has repeatedly asked a simple, eminently reasonable question about his employer's investigation:

Is the NFL aware of any credible evidence - other than the recanted remarks by one individual shown by Al-Jazeera - that indicates that there is any validity to the remarks about Mr. Harrison?
