Tom Brady's Agent -- The NFL Sucks at Punishment ... We're Appealing

Tom Brady's agent just came out BLASTING the NFL -- saying the league has a storied history of BLOWING IT when it comes to meting out punishment ... which is why they're appealing Tom's 4-game suspension.

Don Yee -- who gives absolutely zero damns -- pulled no punches in a scathing statement attacking the NFL and the Wells Report.

"The discipline is ridiculous and has no legitimate basis. In my opinion, this outcome was pre-determined; there was no fairness in the Wells investigation whatsoever."

He continues, "There is no evidence that Tom directed footballs be set at pressures below the allowable limits."

"We will appeal, and if the hearing officer is completely independent and neutral, I am very confident the Wells Report will be exposed as an incredibly frail exercise in fact-finding and logic."

And this is where Yee really begins to spit venom -- "The NFL has a well-documented history of making poor disciplinary decisions that often are overturned when truly independent and neutral judges or arbitrators preside, and a former federal judge has found the commissioner has abused his discretion in the past, so this outcome does not surprise me."
