He still looks hesitant more often than not. His jumper looks fine, but when he gets the ball in the paint he either lacks explosiveness to finish or passes the ball out. You can tell the injury or at least the rehab is in the back of his mind.
Celtics are also mostly ignoring him on offense sets, he usually is spotting up on weak side while Kyrie, Tatum, Rozier initiate.
There have been a few glimmers of hope like the Bucks and Pistons games. When Hayward gets to initiate from top of the key and run a pick and roll with Al Horford he really shines, basically collapses the D on him for a kickout to open shooter or he gets an easy floater.
My opinion from watching is that he's just not going to get it done as a spot up wing and you're basically hoping Brad Stevens puts the ball in his hands more, which happens if Rozier gets traded and Hayward can run the second unit. Otherwise if he gets back to 30 mpg but continues to split usage with Kyrie and Tatum in the first unit I think his line is more around the 14 / 6 / 3 range
