drawbacks

I'm a little stuck... Click here to teach me more about this clue!

'issues' is the definition.
Although both the answer and definition are plural nouns, I don't see how they can define each other.

'even finish champions' is the wordplay.
'even finish' becomes 'draw' (I can't explain this - if you can you should give a lot more credence to this answer).
'champions' becomes 'backs' (as verb - supports).
'draw'+'backs'='DRAWBACKS'

Can you help me to learn more?

(Other definitions for drawbacks that I've seen before include "Disadvantages, hindrances" , "Snags" , "difficulties" .)

I've seen this clue in The Daily Express.
