I give Murray two advantages in that fight 1. A nice high guard 2. Far more championship experience CEJ is bigger than Murray so size wont be an issue for him. Make that 3 3. Proven durability (although I doubt he is more durable to be honest)
I'd much prefer CEJ to revenge/avenge BJS then challenge GGG, but the offer is there. He's asked for it and he has to take it, it will be a terrible look if he backs out now. I think it gets made, and I think at worst CEJ comes out with a greater rep then he goes in with.
Eubank jr has had 16 straight tko wins. GGG hasn't stopped anybody with a pulse before Murray but managed to stop him. Put down the pipe son
