Jaylen Brown became eligible for a five-year, $295 million supermax extension on July 1st and those negotations are expected to pick up starting at Vegas Summer League on Friday.

The Celtics do not intend to make a low-ball offer to Brown and sources continue to insist the two sides will eventually agree on a deal. Boston is also not shopping Brown, who would become ineligible for a trade for one calendar year once he signs the supermax.

There could be some negotiations on incentives.
