When the White House called with an invitation to dine with President Bush, Dan Marino took it. But the coach of his former team said no. Miami Dolphins coach Nick Saban said Monday that his obligations at training camp took priority over a chance to meet the president. "It was really a tough decision," Saban said. "I feel like my first responsibility is our team. That in no way disrespects the importance of the opportunity I would have loved to have had to spend dinner with the President."
