Saric is playing horribly so far.  If he were shooting at all they would be 6-2 or so.  Last night and the Milwaukee loss were both second games of back-to-backs, and the Raptors were home and had rested Kawhi the first game.
Moose was way better yesterday than he had been.  Right now he's a better player than Saric.  Shamet has been very good so far for a rookie.  Fultz was bad yesterday, Embiid was at best average for him, and Simmons couldn't hold on to the ball.  And they were within 6 in the 4th quarter before they ran out of gas.
The key to this season is what it has always been--Fultz needs to become a good, positive NBA contributor or they are not going to beat anyone in the playoffs.  It's really not on Simmons and Embiid, they just can't do what this team needs.
