"ez win" has a tone due to the spelling, and is sarcastic. It's not extensive analysis, but it's a conversational take that brims with purposefully see-thru false confidence used to comment on how crazy that game was.
You said we were up the entire game and then you thought it would slip away.
Upon re-reading your post, you seem to be wrapping that statement is some wider point about being a saints fan. In hindsight, I may have jumped the gun with deeming your post a boring mess. I still don't love your post, but my criticism about it being plain on its face is unwarranted. So you have my sincere apologies and a retraction of my contempt. In this particular instance.
