Anymore the comparing between eras is a moot point. Would Wilt have been as good today as he was then? Many more 7 footers in today's game then when Wilt played. Would LeBron be as good in the eighties, or Bird and Magic as good if they played in the 00's?
No real way to compare, I would say that LeBron and Kobe based on the type of game they play would do well for themselves. Maybe not to the level they're on in today's game but with LeBron's athletic ability, and Kobe's scoring prowess? There's no doubt in my mind that they could be successful in other Era's, but they wouldn't be the "leaders" they're considered today, due to the fact that teams then were 11 men deep.
You could of just said he picked the Lakers, over the Cavaliers. However, I thought Cleveland was more interested in Trevor Ariza at the time, then Ron Artest? The guys that Cleveland went after in the off-season were guys looking to be their own star, not play in the shadow of LeBron James. The guys they wound up with are willing to play the "role player" job.
Aside from money, I really think that's why Boozer skipped town on Cleveland.
