Cleveland completed a trade with the Philadelphia 76ers just prior to making the deal with Andersen in order to make things work under the salary cap
This is false. Cavs could've signed Birdman at any time. Trading away Kaun had no bearing on the Cavs ability to sign Birdman. It'll certainly save Dan Gilbert some luxury tax money, which is good because Kaun is not worth a roster spot, but still didn't stop us from signing Birdman.
I've given up hope that the average NBA reporter will understand the salary cap, but when respected reporters like Woj can't even be bothered to know the rules, we've got issues.
