Like an exciting football match that's lined up? (3-2-3)
I believe the answer is:
end-to-end
'lined up?' is the definition.
(I've seen this in another clue)
I don't understand the rest of the clue.
Can you help me to learn more?
(Other definitions for end-to-end that I've seen before include "in a continuous sequence" , "As things are laid to give impression of distance" , "Needn't do (anag.)" , "From start to finish" .)
