SI.com has an attorney look at the legal angles on the Patriots' alleged ball deflation activities.
If Goodell decides to suspend Belichick, do not expect the suspension to take effect until after Super Bowl XLIX. As noted above, the NFL will likely take some time to fully review the Deflategate accusations and any evidence against specific Patriots coaches and officials. Suspending a team’s coach before a Super Bowl would also be highly disruptive. Obviously, the sports betting community would be up in arms, but of greater concern to the NFL, so might the league’s sponsors. Any action that harsh would not be imposed until next season.
