This has nothing to do with innocent until proven guilty. The ruling isn't about Goodell's ability to impose discipline under the personnel conduct policy, which the panel recognized, or whether he had an adequate basis for doing so, which the panel didn't address because Goodell is the only avenue of substantive appeal on that. The problem is that the league, in listing the different ways that the bounty program could be construed as a violation of various league rules, included among other things the fact that the cash payments could be considered a violation of the salary cap. Even though Goodell can impose discipline under the personal conduct policy, he can't do it for salary cap violations, which are exclusively the provence of a special arbitrator, and the panel (frankly pretty disingenuously) decided that it was somehow unclear which he was trying to do. Declaring victory doesn't mean that Vilma has in any way been vindicated based on the panel's findings, and he's just going to get suspended again.
