Input: Question: Had John Nash worked as a General Manager for any other teams before he signed on with the Trail Blazers? Passage:The 2003–04 NBA season was the 34th season for the Portland Trail Blazers in the National Basketball Association. After years of off the court troubles and playoff underachieving, the Blazers under new General Manager John Nash, decided to rebuild. Throughout the season, the Blazers dealt away talented but troubled stars like trading Bonzi Wells, after losing his co-captain title, to the Memphis Grizzlies in November, and trading Rasheed Wallace to the Atlanta Hawks for Shareef Abdur-Rahim and Theo Ratliff in February. However, after appearing in only one game with the Hawks, Sheed was again traded to the Detroit Pistons for the rest of the season. The Pistons would eventually win the NBA Finals of that year, giving Wallace his first championship. The team also sent Jeff McInnis to the Cleveland Cavaliers for Darius Miles.
