He concedes rebounds, doesn’t defend the perimeter, doesn’t get back on transition. He does not rotate so he expects his teams to read his mind and cover up for him. Lebron is the GOAT in my eyes but at this stage of his career you need strong defenders around him to make up for weaknesses. Lebron has to be the worst defender in the lineup for the team to be competitive on the highest stages. That’s why Reaves and Dlo don’t work defensively with Lebron.
Reaves is decent as an off ball defender and doesn’t miss his rotations and plays passing lanes well. He is awful as an on-ball defender though. He’s basically 2016 Steph Curry on defense.
