There are too damn many lawyers in our society always looking to scrounge a few bucks out of any situation, even if it ruins the Sport.
Powerful Commisioners were first put into place because of the baseball gambling scandal in 1919. Judge Landis was appointed to clean up the mess, and he did, irrespective of whether he was being absolutely delicate and fair. But guys like Sholess Joe Jackson never admitted culpability even when banned for life.
Baseball was on the verge of being destoyed by the gamblers. Trying to prove the cases beyond "all reasonable doubt" is very difficult in situations of "he said, she said", like this.
Because of the godamn lawyers, and the Unions, we have this spectacle of drug barrons corrupting entire countries and governments, without being touchable. Since proof has a way of dying, before it can testify, and meet all the fine points of some bought and paid for Consigliere.
Similarly, today you can't fire any government emplyee in less than a lifetime, as the redtape and procedure ties it up in knots. As a result the government grows and swells and the productivity gets less and less, even when it doesn't turn to pure criminality like the current GSA employee scandals.
Until we recognize that participating in an enterprise like Sports, is a privelege and not a right to be adjudicated, by competing sets of lawyers, dotting every i and crossing every t, even if it takes twenty years, we all suffer. Strong Commisisoners are needed, even if they are not always right.
I'm sorry if Vilma feels he was shafted. Appealing to the courts is beyond the ken. Let him go work in some other footballl industry, like the CFL or AFL, or flip hamburgers; but the NFL Comissioner, like any other sports league Commisioner, should have the power to toss any player out of the league, on his ear, fair or not.
Fairness considerations will come when the owners choose to to renew the Commisioners tenure or not.
