With Don Nelson back at the helm in the Bay Area, he plans on instilling a running style, utilizing the Warriors 'mystery men'.

''Mickael Pietrus is one of my mystery guys,'' Nelson said in an interview with The Mercury News.  ''He will play for me if he does what I want him to do, emphasizing the defensive end and not to worry about the offensive end. He's a great athlete and he can run. And I'm looking for runners.''

''There are other mystery guys; I don't know if they'll be able to make the next move I want them to make. I'm going to need (Troy) Murphy to play some center for us. If he can make some adjustments, he'll have his best year. And it will allow me to play Dunleavy at the ``4,'' because he basically struggles at small forward. He can function offensively better against the ``4s'' in the league.''

''And (Monta) Ellis is a mystery guy. I'm not sure as a high school player (two years ago) if he's ready to play big minutes. I'd like him to, and I'm going to give him the opportunity.''
