Rozier is eligible to extend his rookie scale deal before Oct. 15, but according to Himmelsbach, he will seek the money of a starter - possibly in the $20 million-a-year range. He's due to make a little over $3 million this season.
The 24-year-old has started 16 games in his three-year NBA career, all of which came after Kyrie Irving's injury last season. His exciting, downhill style of play figures to be an important piece off the bench for Boston in 2018-19.
If no extension is reached before Monday, the Celtics will likely extend him his qualifying offer for next season after the campaign ends. He will then become a restricted free agent next summer.
