well let's think of how laz would perform if he replaced yay, i think they play pretty similar and he would do WHO KNOWS! a little worse, same, or maybe even better
It's a false analogy, you're saying that a player is bad because of his team's performance, it doesn't make sense. You need compare individual performance with individual performance, not individual performance with team performance.
Laz is one of the who is few always performing very well on every map against every teams. Few players are like that: Keznit and Yay are a another examples. I'm just saying about individual performing.
