I hate when people say this. The Gasol deal was one-sided, but that's the way the NBA is now with teams trying to clear salary-cap space for money reasons and to possibly sign free agents. The Grizzlies were able to use the cap space to trade for Zach Randolph who became an All-Star in 2009-2010, helping them with 16 more games last season, the most since the made the playoffs three straight years.
Look at some of the more one-sided trades made in recent years and no one ever mentions them because those teams haven't been able to convert those trades into championships. The Spurs got Richard Jefferson, a former All-Star and 20 PPG/5 RPG guy in 2008-2009 for Bruce Bowen (who retired), Fabricio Oberto (who was waived), and 37 year-old Kurt Thomas who averaged a whopping 3 PPG/5 RPG. That was a way more one-sided trade. The Mavs got Caron Butler (former All-Star and 20 PPG/6 RPG), Brendan Haywood (10 PPG/10 RPG) and DeShaun Stevenson for Josh Howard (who played 4 games and got hurt), Drew Gooden (who was waived) and a couple of journeyman. And to top it off, Cleveland got 2-time All-Star Antawn Jamison (20 PPG/9 RPG) and Sebastion Telfair for Zydrunas Ilgauskas who they got back a month later! Talk about getting something for nothing and circumventing the salary cap. At least the Grizzlies got a legitimate center who's worth his weight in gold in Marc Gasol who averaged 14.6 PPG/9.3 RPG last season. By comparison, Pau averaged 18.8 PPG/11.8 RPG last season, is 4 years older and had never won a playoff series before joining the Lakers. They also got Donte Green, a nice young player who they drafted with the Laker's pick in 2008 but they traded him away to Sacramento where he started in 50 games last season.
Jerry West also left the Grizzlies at the end of the 2007 season (June 2007) and the Gasol trade wasn't made until February 2008. Sure, maybe West still had some influence with his successor who's job was on the line after a year. I know my former co-workers are tripping over themselves to do me favors.
