NA- pregameshow and Statistics

It´s really nice to know Sneaky did the 2nd most dmg to champions or that Goldenclue had less impact than his KDA implied...(at least for the statisticnerds among us cough) - so why are those statistics not available on lolesports? For me personally the dmgstats are a lot more interessting to see how a specific pick/buildpath worked out than just seeing who won and what the kda had been. I mean, the statistics obviously are in Riots hands...so why don´t make them puplic?
