Scott isn't the weakest. A lot of people forget that he didn't embrace the fact that he was a werewolf in general. He only used it when he had to protect people, his goal was never to be the strongest werewolf or care about power like Peter and Derek.

He had no idea how to be a werewolf and Derek taught him while he learned on his own as well. But when he embraced his wolf side, he became strong and also stronger than other werewolves on screen as well.

I think we tend to not realize that he was looking for a cure at first and then he just kind of stuck with it. Defeating Peter wasn't luck, it was him realizing that he had to overpower him if he wanted the fight to end. He finally embraced the wolf, but chose not to be murderous.
