Next year's salaries for each of these players:
Kobe $19.5M
Artest $7.8M
Garnett $22.0M
Kidd $19.7M
------------
sum = $69M
by point of comparison, the Lakers' payroll this year was $77M. So yes, it's possible -- but you'd have to get rid of Odom ($13.5M next year), Kwame Brown ($9M), and probably Radmanovic ($5.6M).
FWIW, Kwame's contract DOES expire next year, but so does Artest's. So there's absolutely no gain to the Kings from making this trade unless they are REALLY desperate to unload Artest.
Brian Grant made $15M this year. I assume Pat Riley gave him that crazy contract?
Walton made $1.25M this year, which is not a bad deal. But he is completely replaceable.
