Anecdotal evidence is evidence from anecdotes: evidence collected in a casual or informal manner and relying heavily or entirely on personal testimony. I hope the definition helps. Watching the games you see something different to me, and others have their own opinions, hence why I am saying the evidence you are presenting is anecdotal. I presented statistics to reinforce my observations that Chol is playing quite well compared to Nankervis who had one disposal and no marks in a game (playing as a ruck) and has gone missing in similar ways to Jack and Lynch who play forward. And I see these as fair comparisons as Chol is a RUCK/FORWARD.
Also that assertion that Nank had more marks in one game than Chol's last seven is categorically incorrect. Please do your research.
I agree he needs to play well, but I would anecdotally assert that from my opinion he has been playing well, and the statistics in my opinion back up my arguement.
On the other hand, it appears you have a one dimensional view of Chol which is not applied to other players playing similar roles for some weird reason.
I hardly think he has been given a lifeline. Nank got a lifeline after playing in the same position as Chol and having one touch.
