What Makes you Bronze

Hello my current rank is Silver 1 and I myself do not think I am good at the game. I'm not here to brag about being a little better than bronze, I have talked with a lot of bronze players. Some bronze 1 and some bronze 5 and also in between. I asked about 5-10 questions it varied by what I heard. I didn't what the cookie cutter answer "my team holds me back". i wanted diversity, because we know there is more than just a team that makes a great player. I myself intentionally placed bronze 4 for 2 seasons to see what it was like (wish i had gotten bronze 5 to get down there) I saw the good the bad and the ugly, but every time I managed to get out in under 50 or so games this was done on many accounts because I needed an array of outcomes. This was to see what it was like and how much mmr played such an important role in the teams you get, I would get teams that played better than their rank and teams that fought to the last second of the ff vote. I want to keep this open because i still want to know what makes people bronze what keeps them from climbing to their rank. Because, A youtube video wont get you out of bronze they wont show you in-depth what it is that gives them success, I will be adding on to this.
