The San Francisco Chronicle (Steve Kroner) reports: Dan Dickau’s basketball life has changed pretty dramatically in the past two months. He spent last season with the Clippers, signed with Avellino, an Italian team, in August, stayed in Italy for most of September, and after his deal with Avellino went south, signed with the Warriors on Oct. 1. In Golden State’s 110-95 win at Portland on Wednesday night, Dickau made his first appearance of the preseason, scoring eight points, collecting five rebounds and making four steals in 21 minutes. “I thought I played well,” Dickau said. “There are some things I could have done better but for my first game here, coming into camp late, it was a good building block.” “He’s a very good point guard,” head coach Don Nelson said. “Physically, he’s not gifted but he does the right thing most all the time and when he does get beat, it’s because of a physical problem, not a mental one.”
