On reflection, I would spot content of fake sport that's not breathtaking? (7)

'sport that's not breathtaking?' is the definition.
I know nothing about this answer so I can't tell whether it can be defined by this definition.

'on reflection i would spot content of fake' is the wordplay.
'on reflection' says the letters should be written backwards.
'i would' becomes 'I'd'.
'spot' becomes 'dab' (I've seen this in another clue).
'content of' says to take the centre.
The middle of 'fake' is 'ak'.
'id'+'dab'+'ak'='iddabak'
'iddabak' back-to-front is 'KABADDI'.

Can you help me to learn more?
