My guess is fines to the franchise and major suspensions for Patriots middle men who play no major role with how the team plays on the field.
Suspending Brady would be an extreme move, though I'm sure the majority of people will want him to get suspended (and Belichick, too). The findings just don't seem definitive enough to support suspending a team's best player, for even a single game.

Similar to Spygate, the issue with this whole controversy is that there's no discussion about the degree to which these supposedly nefarious practices by the Patriots are standard practice around the league.
Let's say it is well known and true that Brady prefers his footballs to be a little underinflated, and that the equipment staff indulges him on this.
OK. So what about Aaron Rodgers? Peyton Manning? Russell Wilson? Ben Roethlisberger?
You telling me that Brady's the only QB in the league who has particular preferences about how his footballs are inflated (or deflated), and it's only the Patriots who try to indulge their franchise QB?
Yeah, right.
