That's not what was said. What was said was that EP needs to "buy in". Now, how do we interpret that? My interpretation was they want EP to level up like Yzerman and Crosby did. These guys dragged their teammates into the fight. There was never any question of effort. Teammates looked to them for inspiration. Things like work ethic, passion to win, holding teammates accountable, when giving your best find a next level etc.
Just because a guy is good offensively and defensively doesn't mean he has these intangibles that are absolutely required from your best player if the team is going to be a contender. I think that was JR's point.
