My team gives up

I just played a game where we were all behind and everyone had a few deaths. I feel experienced to enough to tell when a game is going to be winnable or a loss. I can tell clearly later in the game around 40 minutes where the game will go but it seems everyone I'm playing with was where I was back in bronze in the frame of mind that the game is make or break at 20 minutes. Its such a let down in rank where your there to try or to climb or just get something out of it but because your teammates don't want to try or keep hanging on and then your that guy that's saying no to the ff's because they just don't want a hard game. I find my self really wanting close games where I actually feel like its gonna be a good game of skills instead of pub stomping on yas or something.
