No they cannot. why? because everyone has a bad game.for all you know that person has been the top player in every other game but that one. There is no real way to control this. some teams simply get shut down by the other.
Im masters rank and I dont really care.In LP if you win, you win as a team, if you Lose you lose as a team. Im getting kind of tired on everyone wanting to place the blame for a loss. no one needs to be blamed period. The only exception to that is them doing insanely bad. 0-35 in Kill confirmed somethin like that.
