According to Adam Schefter, the NFL has handed out Tom Lewand's punishment for the drunk driving incident last month:
Lions President Tom Lewand will be suspended 30 days and fined $100,000 for violating NFL's Personal Conduct Policy following his OWI.
On paper, that seems like an awful lot, but I certainly don't have a problem with it. Lewand needed to be punished, and it's not like you can withhold a game check and suspend him for a game. It's a different ball game with an NFL executive, but I think the punishment is fine.
