Even after the Holiday and Porzingis trades, I'd probably still do this trade.
So that would be
G: A Simons, Pritchard
G: Mathurin, Scheierman
F: Jaylen, Hauser
F: Obi Toppin, (Horford)
C: Horford, Kornet, Queta
With Tatum to return.
That backcourt feels less comfortable without Jrue there as a controller. Both defensively and offensively. Someone who can bring stability. Someone who could make lineups where we had no defensive liability at guard. And was content just to move the ball and keep everyone else happy on offense.
Pritchard, A Simons, Mathurin are all scorers.
Mathurin offers little ball-handling or playmaking at SG. Puts more pressure on the PGs. A Simons is a limited ball-handling / playmaking PG. Pritchard is okay. I wonder if Pritchard would start ahead of Simons on this squad. Not sure you can afford (defensively) to start them both. Although you might have to get enough ball movement on offense.
Even more pressure on Tatum & Jaylen to provide the playmaking and run the offense. No D White. No Jrue. A Simons not reliable. Mathurin and A Simons are not just guys who provide little playmaking but guys who want the ball in their own hands. Like 4 guys competing for touches / shots.
