Some have suggested that he is similar to Barbosa, which may be true.
Barbosa signed (after his rookie deal) a 5.6 million dollar contract 5 year contract with 500k raises each year, which was roughly 10% of the salary cap. Next year, a comparable contract for Rozier would be 11 million a year over 5 years. With the 8% raises, that would be a 5 year/64 million dollar contract.
He might get more than that on the open market. Just thought I throw the comparable numbers if you think he is a comparable player.
Edit: In the off-chance he signs that kind of a contract and Al is the kind of guy I think he is and will opt out to sign a more team-friendly deal, there's an outside chance we could be under the luxury tax next season, even with Kyrie at the max and resigning Rozier.
In that case, maybe we shouldn't trade Rozier.
