It's not about rest.
It's about Pau playing like he's trying to prove himself.
Back when he joined the team, and got outplayed by KG in the 2008 finals, he felt he needed to prove himself.
So he played two straight seasons like he was on a mission.
Then, these last seasons, you could see it in his play that he's been lazy.
Now, this few minutes, you could see it in his eyes on the possessions that he wanted the ball.
