LeBron IS NOT waiting on the WC to end, he (and the ownership groups that are courting him) are waiting on the Aspiration ruling.
If the ruling comes down and essentially says - “Look, we all know what they did, but we need absolute proof beyond proof in order to avoid a brutal court battle so we can’t justify punishing them” it will have basically written the playbook on how to circumvent the cap.
Even if LeBron has already chosen Cleveland, his official NBA contract number (and the Cavs ability to build around him) will be a direct result of this ruling. Watch him take a vet min and have Dan Gilbert basically dare Adam to find proof of however he’s paying LeBron under the table.
