Bjergsen is not a Player to Watch

cos everyone knows who he is and he has had no competition for a mid laner in NA yet and constantly gets out classed at worlds by everyone and there mum?

Players to watch does not mean best players, it means players who may be great, but we do not know for sure yet. We already pretty know what to expect of Bjergsen. He is the best mid laner in NA, and unless there is some kind of major upset, he will remain the best mid laner in NA this split. There are plenty of other players though that we do not know how good they will be.
