Huge size mismatch leads to brutal hockey hit (video)

This has to be one of the biggest mismatches in size I've ever seen in a hockey game. In a video circulating on social media, what appears to be an adult playing against people much younger than himself, utterly destroys an opponent with a massive hit. Given the difference in size, it shouldn't be a huge shock, but it's still jarring nonetheless. Props to number 7, though. He got up right away and skated off. However, you can't help but wonder if he was thinking too clearly after getting crunched like that.
