Saunders, as much as a il like him, isn't World Class. Chudinov would be embarrassed by Saunders. If Eubank gets in the same ring as GGG ( besides sparring ) i'll swim around Trafalgar Square fountain in a fairy costume. Snr wasn't all that, and Jnr is levels below him. Beating Spike, could be Jnr next and only high profile win.
In which case our views about what constitutes "backing it up" are too different for us to reach agreement.
Have to disagree about Saunders. He is world class - all the more so given that he is a tiny feather-fisted middleweight who should really be at most a light-middle, whose lack of size and lack of pop make his achievements all the more impressive.
Yes, Saunders is where he is because of boxing craft alone, which as stated makes it all the more impressive. Time will reveal all in regards to Eubank Jnr
