  SYDNEY -- He knows what lies ahead over the next few days is far too important.

 So all Steve Nash can do is put his fear of the future out of his mind and concentrate on the Olympic tournament, knowing that a trade might await him in Dallas when NBA camps open in October.

 "I'm happy where I am, but the reality is every NBA player has to be prepared for change," the captain of Canada's men's basketball team said the other day. "I'm not worried, but I'm aware of the situation."

 The situation is that the Mavericks suddenly have seven guards, including Nash, on their roster heading into training camp.

 HIGH TRADE VALUE

 Something will have to give and Nash, who has suffered through a rash of injuries with the Mavericks, has high trade value.

 Complicating matters for Nash, Dallas traded for point guard Howard Eisley earlier in the summer as part of the nine-player swap involving the Utah Jazz and Golden State Warriors. Dallas also has Courtney Alexander, Dana Barros, Greg Buckner, Hubert Davis and Michael Finlay in the backcourt.

 Mavericks owner Mark Cuban remains a Nash supporter and played down the significance of so many guards on his roster.

 "Actually we have fewer point guards," Cuban said via e-mail. "With (Robert) Pack and Damon Jones gone, it's basically Steve and Howard Eisley as our points. We think between them we have a great duo of first-class point guards."
