Anthony Joshua is my favourite HW and I think he is the best fighter in the HW division currently. He has very good resume for 21 fights and helds 3 major titles + IBO. AJ is ranked as number 1 heavyweight in the world by BoxRec and rightfully so. But, according to multiple rumours, he gets beaten badly and knocked out by each and every of his sparring partners. So my question is: does Anthony Joshua stand a chance of beating 42 y.o., 5'6'' Alexis Rafael Castillo Sanchez (0-38, 34 KO losses), who is the worst HW in the world according to BoxRec, in SPARRING? I know he would kill him in few seconds in the real fight, but considering that AJ gets destroyed by everybody in sparring sessions, it might turn to be completely different outcome if they fight each other with headgears and softer gloves.
