Not showing up already has punishment defined in the contract. Therefore, he's not breaching it. It would be like saying taking PEDs is breaching the contract. They have a right to fine him to negate what he'd make per day. But he's not being paid per day. He's being paid in lump sums. By not giving him his money, the Sixers are basically fining him for things he has done yet. When he wasn't reporting, the team could argue they were considering his absence as a statement of intention that he'd hold out. It wasn't a good argument, but it's logical at least. But he's with the team now, and they can't use that same projection. They need to pay him what he's owed and continue to fine him. Otherwise, they're breaching the contract by not following the agreed-upon rules for this situation.
