Janny Hu owns Pree? i kid, i kid
From Janny Hu's article on SFgate.com:
"Not to be overlooked is the huge financial relief the Warriors receive by trading Richardson. Because Charlotte is under the salary cap, Golden State was able to make the deal without getting back the equivalent of Richardson's $10 million salary.
Instead, they netted a trade exception worth that amount which they can now use in future trades without sending back any salary. (Under league rules, salaries in any deal must come within 25 percent of each other unless a team has cap space.)"
Thus, we would have an exception requivalent to whatver Richardson was making, which would allow us to absorb that much of Garnett's salary.
Of course, we'd still have to send Harrington's contract, Sarunas' contract, plus Wright and Ellis for talent
A Garnett trade just makes a hell of a lot more sense, since Garnett makes us a better team immediately, while Wright would have required a couple more years.
Anyone else have sources to confirm or deny?
