Owen Crisafulli thinks it would only take Derrick White and some picks.
https://hardwoodhoudini.com/2022/06/25/boston-celtics-conley-brogdon-trade/Here's Brogdon's bonafides:
NBA Rookie of the Year (2017)
NBA All-Rookie First Team (2017)
50–40–90 club (2019)
Consensus first-team All-American (2016)
Consensus second-team All-American (2015)
NABC Defensive Player of the Year (2016)
ACC Player of the Year (2016)
3× First-team All-ACC (2014–2016)
2× ACC Defensive Player of the Year (2015, 2016)
Even though Brogdon was injured last year, he's healthy now and is a strong, strong defensive player.
I'd be willing to give up White, PP, and a future first-rounder with a pick swap in a future year.
Brogdon would replace White in essence, and a backup PG like Goran Dragic could be attained.
Brogdon was a BIG loss for the Bucks two years ago. He could be the piece to take the Celtics over the top.
