It actually emphasised my point: most teams don't win a trophy; most don't win one often. We have only ever won one major trophy.
If this is a "unique opportunity to break the top 4" then I'll definitely take the cup. Now if it's an opportunity to get top 4 and progress to a club that gets top 4 every year, that's a different story.
(Before you bite, my second point is taking the piss

)
It is interesting however that in your final paragraph, you mention that you lament coming second as winning is better... I wonder how you'd feel in 20 years time, if we came 4th this year and didn't do it again or win a cup? I bet you'd lament not winning that cup you were offered

As you said though it is just a choice, but a good debate (not argument) all the same .
