A few comments from a Laker fan.
Kwame Brown is the whole point the Grizzlies even considered trading Gasol to the Lakers. He has a $9.1M expiring contract. The Grizzlies are looking to save money due to sagging profits ($20M loss this year), and they may even want to be there for the big FA pool this summer to build around Rudy Gay. If that's the case, there is zero reason for the Grizzlies to want much more talented players from the Lakers or any other team for Gasol (like Odom). Odom, for example, has $22M left on his contract (pro-rated), so it makes more sense to pay Kwame his pro-rated $4.5M than paying Lamar, saves $17.5M and LO isn't close to an All Star this season to boot.
Crittenton was also an important consideration. Financially he's a sweet deal, as he's a rookie and therefore is locked into his contract at $2M per year until 2011. He has huge upside at just 19 years old. For those who don't know who he is, Laker brass and Laker fans have been high on him all year. Sad to see him go, but obviously you do a deal like this when you're talking about a 27 year old All Star PF/C that is triangle matchup nightmare for opposing squads. So Kwame Brown the player is irrelevant, anything he gives them is merely window dressing, because they're NOT looking to get equal value back, they know they won't get it. They traded for Kwame because of his contract, which NO other team in the league could provide that also was wiling to give up a young prospect like Javaris Crittenton. Gasol also has about $50M of guaranteed cash remaining on his contract, and Buss is one of the few owners in the league willing to commit to paying that kind of money.
Btw, there is also precedent for superstar trades for expiring contracts + scraps, at mid-season (like now), and just in the last 3 seasons too. For example, superstars like Vince Carter were acquired for Mourning, draft picks, and expiring contracts. Tracy McGrady was traded for a huge contract in Francis, Mobley, and expiring contracts. Rasheed Wallace was traded for reserves and draft picks. And both Carter and Wallace were deadline deals too, just like this one.
Collusion? Nope. Just a lot of great scouting and the magic touch of Jerry West
finally rubbing off on Kupchak after he and the FO were a disaster of a management team between 2000 and 2004. 2005-2008 has been very West-like, to say the least, a complete turnaround in philosophy from slow, shoot-first mediocre athletes to athletic, skilled 2-way players.
