it's not a valid argument tbh. You can only judge someone based on what he has shown.
Like if you make an argument for 'he couldn't have', I could make an argument for the opposite. It's pointless.
but tenz has only shown in the group stage????
yes group stage wise hes a top 10 player, but group stage + playoffs u cant say anything because u cant judge if tenz can be consistent or not, so u really dont know if tenz would be up there for sure, so yes u can say hes a good player stat wise if u ONLY look at the group stage stats, if u look at group stage + playoff the sample size is too small
