All Some eyes are on NFL headquarters in Manhattan this week, as the Tom Brady-Roger Goodell deflated footballs adventure takes its next step: Brady's appeal of the four-game suspension handed down by the league in the wake of the Wells Report on the possibility that the Patriots intentionally underinflated footballs during a playoff game in January.

Yeah, yeah, this is still happening. The appeal proceedings began on Tuesday. There is no timetable on a verdict from Goodell, who -- amazingly -- is acting as arbitrator in the case.

Here is a quick rundown on what's going on at 345 Park Ave.

The circus

The entire Deflategate saga has been a joke, so it's fitting that the scene outside NFL headquarters Tuesday was something out of an Onion article.

Patriots fans congregated alongside and in front of the bevy of news cameras. They held signs that read "Free Brady" and "The Foxboro Witch Trials." One man reportedly told his boss he couldn't work because he had to take care of a "family" issue.

The courtroom

OK, so it's not really a courtroom. It's actually nothing like a courtroom, and it's not a trial, though the proceedings have taken on a decidedly litigious dynamic.

The thing about the Brady case is it's shining a light on the NFL's appeal process unlike any other in the league's history, one that is normally shrouded in mystery. People don't usually care -- especially to this degree -- when a player appeals his punishment.

University of New Hampshire law professor and Sports Illustrated legal analyst Michael McCann told Boston sports talk radio station WEEI that the dealings Tuesday were going to be more "business meeting" than "trial," more fluid conversation than formal presentation of evidence.

That said, Ben Volin of the Boston Globe reported over the weekend that the sides would take turns make their case.

"There's really no back-and-forth at the same time," a league source told Volin. "The appellant makes their case, then the league makes theirs, then the appellant gets to rebut it, then the league gets another chance, then both sides have closing arguments, and that's pretty much it."

Joining Brady, according to Volin, was agent Don Yee, NFL Players Association executive director DeMaurice Smith and a few lawyers, including the NFLPA's Jeffrey Kessler. That group was expected to point to the Wells Reports' faulty science and the fact that it never came close to proving Brady was at all involved.

With the NFL was Adolpho Birch, the NFL's senior vice president of labor policy and government affairs, and several lawyers. They were expected to simply point to the Wells Report and remind Goodell that Brady wasn't exactly helpful during the process.

Ted Wells -- who ran the NFL's four-month, $5 million investigation into the possibly slightly deflated footballs -- was also expected to be present.

One of the biggest differences between this appeal -- a private matter between an employer (the NFL) and a union (the NFLPA) -- and a trial is that it is indeed private. Or supposed to be. There are no cameras in the room and no reporters live-tweeting, so any information that comes out is a leak -- and since it's the NFL, there are plenty of leaks.

One bizarre dynamic was that of Goodell himself. While he commissioned Wells to investigate, then approved of Brady's punishment before it became official, Goodell was technically an independent third party, the de facto judge in this pseudo-trial, as mentioned.

"[Brady's] union gave the commissioner almost unlimited authority to regulate player conduct," McCann told WEEI. "That is probably Goodell's best skill in this meeting, that he has this sweeping authority."

The result

As of Tuesday afternoon, no one knew what Goodell's decision would be or when it would come. There was plenty of speculation, though.

Goodell's options seem to be:

• Don't change Brady's suspension and make him sit out four games.
• Lessen Brady's suspension to 1-3 games.
• Eliminate Brady's suspension.

No one in the know seems to think the third option is likely. There is some belief that if Brady was more forthcoming during the appeal than he was during Wells' investigation, Goodell will reduce the suspension.

If and when Brady's appeal is denied, it's possible the quarterback could take the NFL to federal court. The concern there, McCann told WEEI, is Brady would have no control over the schedule and it could result in his suspension taking effect midseason or later, even spilling over into 2016.

In other words, there is a very real chance this farce of a controversy isn't close to over.
