Former Miami Dolphins fullback Rob Konrad apparently fell off his boat off the South Florida coast but arrived safely on shore early Thursday morning after swimming at least 10 hours and nine miles through the Atlantic Ocean waters, according to the Coast Guard. Konrad was wearing only his underwear when he approached the driveway gate of 1800 S. Ocean Blvd. and told a Palm Beach police officer working a security shift about his incredible experience, a Palm Beach police report says.
