Let me spell this out plainly and slowly ...

You asked: Was the moment huge.  And you then answered: Yes.  So, by all accounts it was epic.

See, epic means this: impressively great.  Yesterday was a lost opportunity to do something inpressively great -- win a share of the Big Ten Regular Season Title.  We haven't won too many of those the past 20 years. 

So, we agree it was epic.

Choke Job figuratively means to turn a virtual win into a loss.  Up by 5 with 52 seconds left to play, at home with the season on the line, miss the front end of 2 1-and1s by your premiere players, and then lose the game.  That, sir, is a choke job.  Choke jobs do happen, as you say.

Put them together, and you get an epic choke job.  In the end, it is just another regular season, but it could have been a special, or rather epic, regular season.  Sigh.

Now, do I wish we would have won?  Of course I do.  Will you allow me to call a rose a rose?  That's your call.  But, really, calling it dumb just reflects poorly on you.
