It sort of does. That a selfish player would average 5 assist per game is a contradiction in logic. Now Landry, averaging less than 1 assist even when he was playing 35+ minutes, that's selfish!
Teamwork leads to assists. But getting assists doesnt mean you have good teamwork. With Reke i tend towards the latter because imo they come from selfish takes and bailouts from teammates. I dont think that hes completely selfish, but he does have seem to have a lot of moments that makes me doubt his awareness of his team.
