Yorick bugged?

I was playing an ARAM and at the end of the game I looked at damage dealt to champions and damage taken. There was a Yorick in my enemy team that did more damage to champions than our entire team together actually took and he also took more damage than our entire team actually did. Now I can imagine that he would've taken more damage than we did to him but doing more damage to champions than the actual champions in the game together took is out of the ordinary. Please check it out because I'm not sure if this happens more frequently in the game. I linked the match history of the game where this happened in.
