I would never have suggested to trade Kobe IN-SEASON during '03-04. The Lakers, when healthy, were the team to beat that year.
I'm suggesting that the Lakers should have worked out a sign-and-trade POST-SEASON '03-04, leveraging that only in that manner would Kobe get the maximum salary, along with the ability to sign for 7 years. Anything else, Kobe would lose a 3% salary increase per year (can't remember if it's 10% vs. 13% increase, or 7% vs. 10% increase, but it's 3% difference), and would lose a year off of his contract. Plus, and I'm not sure if this would fit Kobe's situation at the time, I'm pretty sure there's a difference between what the current team can offer and a new team can offer based on what the last contract was - which means it's important to get max-dollars and bigger raises now just to get better contracts later. That's a significant amount of money. Kobe hadn't yet realized he couldn't carry a team by himself, and the money - especially in the light of the rape case and him needing to rebuild his image after losing endorsements - would have played a big part. The Lakers wouldn't have gotten equal value for Kobe, but they would have gotten reasonable value - enough to, say, keep them competitive in 2004-05.
Kobe's own ego would have tripped him up...he'd be willing for the team he was going to to dump a superstar just so he could have the spotlight - because - and this is important - the only reason I'd have gone this route was because KOBE WOULDN'T RE-SIGN IF SHAQ WAS STAYING. If Shaq wasn't an issue, there'd have been no need to trade Shaq just to get Kobe to re-sign. In other words, the initial difference in attitude would have long-lasting repercussions in addition to the immediate issue at hand.
