I like SM but the credentials of his team as a whole might be questionable until things settle down with a win or two. By this time under IB and LW, we'd seen interviews with Maurice Ross and Ryan Harley, so I think it's time Matt and Craig Saunders did the same.
As for subs, I much prefer SM's on-a needs-basis approach so far, than LW's mass substitutions for the sake of it. They very rarely worked out well anyway.
