hi all, i'm currently writing a research paper about the history of baseball sabermetrics, and i was trying to take an e-sports approach to part of it. I was curious about the history of analytics and stats in competitive tf2, since I wasn't around when these things were first being developed, for instance

-how was the initial reception to sites such as logs.tf/sizzling stats, were people excited by the idea/implementation, or was there a worry about people "playing for logs" or other concerns?

-Who were the first people to look deeper than in game points to review performance, and was there a reason these people first did this?

-Were stats that are held commonplace today like dpm or uber drops always around, or did someone have to come along to develop and popularize them?

-From what I can tell, when looking at overall "how good a player is" (i.e., who is a better roamer, blaze or seagull, etc.) career statistics are given less of a value than team performance, seasons/tournaments won, how well they played with their team playstyle, and other factors. How much of this do you think is attributed to the nature of a team based game such as tf2, or do you think there may be other factors at play?

-Projects have been in place to look at player performance such as TF2Metrics (props to the devs of this btw, it's really impressive), fantasyTF2, and a site that keeps track of career performance and records that I can't remember the names of off hand. How much weight, if any, do players place on these to review their and others' performance?

-Have you personally, or have you heard of anyone that has changed their playstyle or mentality around tf2 as a result of statistical reviews of logs or other factors?

-any other thoughts you might have about statistics and metrics in tf2 or any other esports are also appreciated.

thank you in advance friends :)
