Maybe that was because Favors and Kanter imposed their will on Gasol and Randolph in the first quarter defensively. They played physical, the refs let it go, and Memphis wasn't used to it.
Marc Gasol and Zach Randolph are not used to physical play? Really? Even I know better than that.
Yes, Favors and Kanter got their way most of the night. To me, it looked like a lack of effort on the part of Gasol and Randolph on the defensive end, rather than being physically over-matched.
