I saw a kid trying to bang with Gasol, but ultimately not having the strength to do it well. Not many of his rebounds were contested, from what I recall.
I was suprised by some of the strong moves Gasol pulled on Kanter. I am used to im being a finesse player. So basically your complaint is that Kanter is to young to guard Gasol. Great! He will be fine then. As for rebounding he has a good game but it was only 1 game. If he maintains that average then we are talking.
