HendoWinston Biscuit Rooney very much throwing his hat into the ring for the Everton job (was there ever a time where actual hats were thrown into actual rings when someone wanted to suggest they were the person for the job?)
https://www.phrases.org.uk/meanings/throw-your-hat-into-the-ring.htmlThe ring in question here is a boxing ring. These, of course used to be circular spaces in a crowd of onlookers, rather than the square, roped 'rings' of contemporary pugilism. Any Jack the lad who fancied his chances in a bout would throw in his hat - presumably this was a more reliable way of putting oneself forward than just shouting over the hubbub of the crowd.
I think Rooney can show his rivals in a fist fight as well. Time will tell how well suited he is for the job.
