The LCS splits stats and Playoff stats are combined

I'm a stat enthusiast in my spare time I try to find out LCS players all time stats. There is a few problems to this

A. the 2016 Regular season Split stats are combined with the Playoff stats not to mention the Challenger players stats, how annoying to try to calculate for example Bjergsen's stats for the 2016 spring splits are also combined with his playoff stats.
B. I was watching a 2015 spring split game for the NA LCS and I while I was watching I saw an ALL-Time Leader board of certain players stats for the desk announcers to talk about. I can't remember what game or what topic of stat it was so I won't " " it but it was something like

CLG vs C9 game and the shout casters were talking about Aphromoo's all time Assists and how he was getting closer to become the #1 all time Assist leader. I tried to find the board but I can't I also can't find that game so this topic can be easier to explain.

IF anyone knows where this Board is I would appreciate it ! Thank you and Have a Good One !
