1. Collins is not an "awful defender".
2. Kessler was benched because he was a huge negative on the offensive end.
3. Kessler was also benched because he can't defend on the perimeter which is Gobert's biggest fault too.
4. Kessler was benched because he didn't improve AT ALL from last year.
I guess some with a huge mancrush on the guy wouldn't see that though.
