Dolphins coach Tony Sparano isn't happy with the off-field issues the team has dealt with this offseason. Miami running back Ronnie Brown became the third player arrested since early February when he was charged with driving under the influence of alcohol last weekend in suburban Atlanta. "I'm obviously not happy with any of this," Sparano said. "That is for sure. I'm absolutely not happy with any of it. Any time any player -- anybody -- brings a negative light to the organization in any way, I'm not happy about it. Those things have been addressed. ... "A few of the players that have had these issues as of late have been model citizens since I've been there and, really, for a long time in this league. From my end, I do take that into consideration."
