This is not something that would ever happen to a cash game or sit and go player because one random win does not effect the bottom line in a noticeable way. If you take one single win out of a player’s history, the chances are that their overall ROI will drop by a noticeable margin. Since tournaments are inherently full of variance, the actual rate at which any given player wins is near impossible to decipher. The biggest obstacle for tournament players is being able to pin down an actual win rate. Long term tourney winners will only be able to maintain a profit if they are able to play well on a consistent basis. When it comes down to it, there is no disputing that MTTs require skill. The argument doesn’t revolve so much around whether there is more skill than luck, but instead whether they luck is outweighed by a wide margin.
One of the oldest debates in poker is whether tournaments are more skill than luck.
