Today in Sports: Remembering the Dream Team, riots at Euro 2012, and another warning for NFL players.

• More than 180 people were arrested before Tuesday's European Championship match between Russia and Poland in Warsaw and the Russian soccer federation was find $150,000 after fans both in and out of the stadium displayed giant banners saying "This is Russia" and others carried old Soviet flags. The signs were seen as provocation to the locals after decades of Soviet control over the country during the Cold War. Both sides did battle with each other and with riot cops.

• Following the DUI arrest of Super Bowl winning lineman Dave Diehl, NFL Commissioner Roger Goodell sent a memo to all his teams today reminding them to not let their players drive drunk. It's a persistent problem for the league and one that contributes to the image of pro athletes as lawless thugs. (It doesn't help when fellow players defend their teammates after such incidents.) Goodell's memo says that, "Every negative incident undermines the respect we have earned from our fans, erodes the confidence of our business partners and threatens the continued success of the league. As your club concludes its mini-camp, it is essential that you take time to reinforce this message with your staff and players."
