After a record 73 wins and a memorable Game 6 comeback on the road, the Golden State Warriors' goal of getting back to the NBA Finals and defending their title comes down to Game 7 at home against the powerful Oklahoma City Thunder. All along, the Warriors have said the numerous team milestones and personal accomplishments they set during this special season won't matter a bit unless they repeat as champions. ''I've learned that our players are tough, they're mentally tough,'' Coach of the Year Steve Kerr said Sunday, when his team took a day off from film and practice.
