Well, I'm new doing ranked and I was surprised when, my team won the 5 games to enter a league and we get Bronze III. A friend told me that they with only 4 victories in the first 4 games they were Silver IV.
So I was wondering that what factors influence to get in a League, because it's not only how many wins we do at first 5 games.
The personal MMR from every one of the team can be a factor?

Here's what I know, I'm sorry if it's not a complete answer.
In 5v5, everyone's elo is important, because Riot will match you against a team with similar elo. This is important because it's not just winning that matters, but who you win against.
For instance, if you win 5 games against 5 Bronze III teams you'll be placed into Bronze III-II. But if you win 3 games against Gold 3 and lose twice against Platinum or Gold I, you'll likely be placed into gold.
In short, it's not just the quantity, but the quality of wins that matters.
