The thing about the average Low MMR player is that while they may make mistakes, your also on the same team with people making those mistakes. And usually when these people get ahead they believe they are unstoppable or thet there is no possibiility of a comeback, leading to a lack of capitalization and enablement of the enemy team.

Normally, people like to use champions that they THINK are OP or stompy, so thats one of the main reasons. Overconfidence.

Not to mention, a lack of range leashing and poor knowledge of champion dynamics.
