It's nice to see a guy wanting to play for the C's so bad that he's lamenting not signing after signing with another team for a lot more. i guess Lue and KG aren't that good friends. KG could of covered the 600k. Might of brought his salary under 25 mil though 
The measly "600k" will cost the club 3 million. Welcome to the wonderful world of luxury tax.
U already used that poor math before. The luxury tax isn't 5 times the amount. Also, you can't blame every player on the luxury tax. Are u saying kg costs us 50 mil or scal 6 mil a yr? I know how the luxury tax works (and its not 5 times), but you don't buy a porsche and then ask for hub caps instead of rims to save a litle in the end. And my KG 600k thing was a joke with KG just giving it toLue under the table, which has nothing to do with the Celtics. Personally I'd rather keep House. Even if that means giving House another 600K
The math isn't so far off.
Here's how it works. If the Celtics sign a player for the vet minimum, they're only responsible for roughly the first $800k, no matter what the actual contract is (in Lue's case, roughly $1.2 million). The NBA actually pays the rest. Also, that $800k is the only amount that counts against the luxury tax.
So, if we sign Lue to a vet minimum contract, we're only on the hook for $800k, plus another $800k that we pay because we're over the tax limit. Thus, $1.6 million.
If we sign Lue for $1.8 million, we don't get any reimbursement from the NBA, and we pay another $1.8 million for luxury tax.
So, in actuality, the difference between a $1.2 million vet minimum contract, and a $1.8 million LLE contract, is $2 million. Obviously, if you gave Lue a second year, the disparity becomes even greater.
