No we couldn't. I'm not trying to be an ass, but I don't think you have an understanding of the NBA CBA.
First, his extension doesn't kick in until 2024/2025, so the extension has absolutely nothing to do with our current salary cap.
So lets talk about the differences between Team B and Team C, just in terms of finances.
Team B - He takes up 22% of the total salary (if you want to call that "most", go ahead). Because you can go over the cap to sign your own players, KAT does not preclude us from re-signing any of our guys.
So let's go to C.
We somehow remove KAT from the books (we traded him last year for a person expiring) and he is now OFF the books completely.
Our salary cap hit would be $113 million (same team without KAT).
The salary cap is $123 million - so we now have $10 million dollars to play. However, because we are not over the cap we would NOT qualify for the MLE or bi-annual MLE.
- So without KAT we have $10 million to play.
Now with KAT, we would be over the cap we qualify for the MLE, that is over $10. So we would have the $10 million to spend on free agents.
