Tom Brady's Deflategate suspension upheld! Right decision?

NFL Commissioner Roger Goodell has upheld the four-game suspension of New England Patriots QB Tom Brady. Goodell writes that “Brady engaged in conduct detrimental to the integrity of, and public confidence in, the game of professional football.” In his comments, Goodell suggested that a key reason for upholding the suspension was that Brady destroyed his cell phone - which was considered to be evidence - shortly before meeting with NFL investigators. Do you think Goodell made the right move in upholding the suspension?
