“Today’s NBA it is more of a challenge,” Walton said. “Julius is very good at that small-ball switching, which a lot of games turn into in the final five minutes. Larry has been really good this month, as well, with that stuff. So it is not that Brook can’t do it. … But in fourth quarters, Julius is the No. 1-rated defensive big man in the league for however they keep that switching stat and keeping guys in front of him and not letting him score.”
