NFL Upholds Suspension Decision

Legendary NFL New Orleans' Saints' head coach, Sean Payton, has been suspended begining April 16,2012 until April 16, 2013 for failing to comply with NFL bounty rules and regulations. The team as a whole was fined a whopping $500,000 and the 2nd round draft picks for the next 2 years. The decision to suspend Payton was appealed, but ultimately upheld and it looks like the Saints have a few options as to who can fill this position. However, my question is was this neccessary? Yes, we understand that there compliance elements behind all the touchdowns we see on TV, but to suspend a coach of this caliber for a whole season? I can't say that I see why this is absolutely necessary.
