I see it as saying two things, perhaps one unintended...
First, that Spooner put forth an effort that yielded a result. A change from a previous effort or assertiveness level, emblematic of the greater state of the team, not just him as an individual.
Second, that Claude has recognized this previously, and thus does not have the sway or influencing factor to actually motivate his players to physically place themselves where they need to be... in front of the damn net. That this drive is left to the player's own determinations is an indictment of his methods or effectiveness as a coach and leading personality.
