Honestly, don't you find it a tad unrealistic for a non-wrestler like this to knock Jericho out in one punch?

Yes,seriously he just beat three men then gets knocked out by one punch.Actually I find the whole storyline in general unrealistic.I mean we all know Chris Jericho does respect these legends.Like Steamboat said he wrote about the respect he has for them in his book.Jericho obviously respects these legends.I think the whole storyline is really out of proportion.
