The extension news is big for Jaylen. It greatly increases the chance that he’ll resign with or without the supermax, and as it takes effect this summer, as opposed to 2024-2025 when the current CBA would have originally expired, it feels like it was made just for him. Because the Celtics can offer him larger raises than other teams, an extension signed this summer under the new rules would likely be larger than a 4-year deal he could sign in free agency with another team in July 2024.
The other big news to me is that there is no mention of cap smoothing in advance of the new media deal. Maybe they’ll save that one for when the new deals are signed, but get ready for a giant cap spike (upwards of $75 million from one season to the next) in a couple of years.
