Agreed with this.Maybe not but I think it's pretty clear he's not a good defender. Even if Kanter is average, they should still be looking for a defensive big.
It's also possible that big is already on the team if he could just stay healthy.
The eye test is not great, but he is better than expected to me...and still not good. He's not a black hole, and the effort is there. He has absorbed a lot of what Brad coaches, but they give up more easy baskets due to bad reads and poor footspeed in space.
A defensive big rim runner with hoop IQ is ideal for this particular team. But I'm on team BH as far as paying through the nose or reconstructing the whole thing mid season.
