Anyone who fights anyone anywhere for any amount of money and gives a good account of themselves every time out is good for boxing.
I'm not a particularly big fan of his, but yes Joshua has had a massive popular impact on the sport in the UK and globally, and has consistently taken on the best fighters in the division when said fights could be made. He's the epitome of a great champ who did exaclty what he was supposed to do, whatever people may think of him now.
David Price - one of the most entertaining fighters around, his fights usually end in a knockout, always willing to test himself against the best, a lovely pleasant bloke outside the ring.
Spot on actually, particularly where UK boxing is concerned. Imagine the furore if he actually ended getting a world title shot, stranger things have happened.
