I'm usually the first person to defend the coach (any sport). I'm well aware that, in addition to knowing the game better than we do, our Coach has far more intimate knowledge of the players than any of us do. But in this case, I've watched Monty do this in the past. And he has, on at least two occasions, admitted to the press that he completely forgot about one of his bench players and regretted not using him in hindsight.
So, knowing he locks in on his main guys and loses sight of his bench, I can't help but get concerned when I see clear needs that could perhaps be solved by using on of his deep bench guys. I think he's a great coach but they all have weak areas and no coach can do it all. I think he needs to put an assistant in charge of reminding him about options beyond the starting 5 and the first 2 or 3 off the bench for those situations and matchups that warrant it.
