The Fort Worth Star-Telegram (Jeff Caplan) reports: Gerald Green, a former high school prodigy out of Gulf Shores Academy in Houston, has agreed to a one-year contract with the Dallas Mavericks, Green’s agent Colin Bryant said. A first round pick of the Boston Celtics in 2005, the slender, 6-foot-8 Green was part of the trade that sent Kevin Garnett from Minnesota to Boston. The Timberwolves traded Green to Houston last season. He played in one game for his hometown team before being released. Bryant was on his way to Dallas on Wednesday morning to work out the specifics of the deal.
