Well he basically just reiterated that he's gonna play the guys the same way again this year, not go deeper. Actually he has basically said he wants to play a smaller rotation this year than last, so not sure that goes with what you're saying.
As for not being successful with that philosophy, his most successful season was actually the year he also went with the smallest rotation, so doubt he sees it the way you do. He went 7 deep his final year at Missouri state, and that was by far his most successful season as a coach.
Martin has never had the luxury of coaching otherwise.
