From what I've seen... He just doesn't seem on Linares' level. I think he'd struggle with Crolla... I do think he could snag a world title if he fought a weak champion though!
I hope he surprises people and performs better than expected, if Mitchell can drop linares then campbell can too
Don't know what Hennessy was thinking putting this fight on Youtube PPV. Youtube PPV is unproven and therefore the public won't want to spend money on something they are not sure about unless it is a fight with two very big names who people want to see. Parker isn't anywhere near a big name here and Fury is only somewhat known because of Tyson. Even then, Hughie whilst being a good fighter isn't an exciting fighter and therefore hasn't got a big fanbase. Because this fight is on Youtube PPV, the few people who may have paid to see it on Sky or BT ppv or whatever will get put off and won't bother paying to see it. Terrible idea from Hennessy, would only work if it was a Joshua fight or a fight of big demand from the public. The undercard may be free to watch for now or whatever but it certainly isn't a very interesting one.
Campbell does have a chance, but i believe that Linares is the better of the two and will win in a competitive fight.
