I've never seen a worse Zed
Clearly you haven't watched this game on the season so far. And if you don't care about watching the video, here's the match history for that game.
Hai with the Zed pick (being 2-0 on it prior) was a risky move in itself not to mention it being a blind pick into the mid lane Zilean match up he got. You talk about how it was Zed being unable to kill the Jhin with no peel...but what about the rest of the enemy team? What about the team compositions both teams had and where the best and worst points would be in order to even engage? It's not easy to rock Zed when even or late game without the proper means to initiate.
