The first trade I'm looking at is the Rockets. They have plenty of cap room and might be willing to take on a contract for a 1st. We got an extra for with the Smart trade plus we've gained multiple 2nd round picks over the draft. The Celtics do this trade by getting a young player who's signed for 4 years. Porter Jr. could play 1-3 but he's a great play maker and could be the full time point and run well with White. Rockets do this trade to get a veteran in the locker room and also run the point when back. Granted this trade only really works if Harden doesn't go to the Rockets. With Brogdon they also receive a 1st and a young point guard they can use with Pritchard.
Celtics trade
Malcolm Brogdon, Payton Pritchard and a 2024 1st pick.
Houston Rocket trade
Kevin Porter Jr.
The second trade is a sign and trade with Dallas. It seems they have some interest in Grant Williams and they have two players I'd be interested in. Bullock give's us a tough small forward defender and can score when needed. Jaden Hardy is a young player ,signed for 2 years still that can play the 1 or 2. Grant gives Dallas a stretch four that would play well next to Luka
Celtics trade
S&T Grant Williams, 13-16 million a year
Dallas
Reggie Bullock and Jaden Hardy
Starting 5
C- Williams
PF - Porzingis
SF - Tatum
SG - Brown
PG - Porter Jr.
Backup 5
C - Horford
PF - Kabengele (Sign to a main roster deal)
SF - Bullock
SG - White
PG - Davison (Sign to main roster deal)
Back of bench rotation
PG, SG - Hardy
C - Kornet
SF - Hauser
SF - Jordan Walsh (send him up to Maine)
With free agency could bring in a better piece for the bench to replace Kabengele and Davison, but I personally keep them on the main roster as cheap players. If looking to bring in another cheap center and someone who the fans would love to see again Tacko Falls. In China he's been playing really well and would be a good spell center for 10-15 minutes a game to keep Williams fresher.
