As much as many wont want to see him get another pay day there's still quite a lot of fights out there for Saunders if he was to carry on...

Rematch vs Eubank Jr with their bad blood could be interesting....Jr is possibly a more refined boxer since their first.
Callum Smith for the bragging rights of best in Britain at SMW.
He could probably have a go at Golovkin, get on his bike and nick a points win
An ex champ to feed to Benevidez, Munguia or Charlo?

This loss doesn't make him irrelevant in and around the middle division...and we all know he has no shame, so won't go into hiding fully....of course his attitude and dedication to the sport might change some. Time will tell.
