No one operates at 100% in game 84, not even Pete Rose. Sure, he operated at a higher level than most but no human being operates at 100% all the time. We're literally not wired to work that way, our brains actually can't maintain that kind of frenetic pace in perpetuity (thanks, mammalian ancestry!). Expecting an athlete to maintain 100% intensity for 3 hours a day, 162 games a year is unreasonable. That doesn't give players an excuse to skate or loaf when there's a legitimate chance to make a play but it does mean I don't get too worked up when a guy jogs out an IFFB in June. Give me a good, solid effort 100% of the time. When it really matters that you leg out that extra inch or throw the ball just a little bit harder, lay it out and go for it... but no one should expect the latter effort day in, day out of a 162 game season.
