This is not his fault.
I would say that it is not his fault that the team isn't in the top-4 in the East. The roster is not a contending roster right now.
But the fact that we continue to have the same issues every game without any notable signs of improvement falls on his shoulders. This league/conference isn't a juggernaut this year. We have had plenty of opportunities to capitalize playing against teams with incomplete rosters, poorly constructed rosters, etc, and we can't get any points. That falls directly on him.
