Just acknowledges that the fit for all the players may not be perfect so the coaches have to tweak things in the system. One of the big criticisms of Lefty/Beamer was he stubbornly stuck to their system irrespective of the players available. While I thought that was largely overstated and simply manifested itself differently because the system was a bit more rigid, that was the criticism. Now, we have a coach with a more malleable system where the adaptations are more obvious, so it’s not a criticism to say he molds things to suit his players while recognizing if he’d do things differently if he had different players.
