Trading them both would be a terrible waste of development when you consider the time and $$$ invested in them.I'd say we either keep 'em, or trade them both and go full rebuild. Can't go half-pregnant and keep Matt and lose Brad.
What would we get in return - draft picks and start again? No thanks.
Only way I would trade them is for 2 x 100 game midfielders who have either been or potential to be AA.
