I suppose each is entitled to their opinion, Appleby does have weaknesses, such as his defence etc, but is he that far behind Mitchell really? Other than Johanneson, Mitchell has faced a similar level of opponent, and has he really disposed of them all that much better? After 26 fights, you would have thought he would have been able to work out a defence by now - he does have heart, but that ain't always enough.
I would have been worried about those middle rounds if Mitchell was 28, but he's just a kid really. It's amazing to think he's only 23, he seems to have been around forever He's been brought along very cautiously, that was his first big step up. The potential is there, he has a good all-round skillset. Needs to use his head a bit more, and realise when to fight and when to box There are a couple of tough domestic fights, with the likes of Foster Jr for him. Then perhaps European level, and a potential fight with Alex Arthur. Then we'll get an idea of his standing in word level
