I think we are being a bit unfair to Jonno...
All the top names have had fights where there has been a gulf in experience, but the thing that makes this exciting is that it is literally down to the luck of the draw.
It also comes down to the mental preparation of the fighter, cos if people see Jonno as not much of a threat, then they will under-estimate him, and he will always have a punchers/kickers chance.

There is always gonna be a gamble, whether its fighting domestically or internationally. Fortunately, or maybe unfortunately, there is scope for discussion on this matter....BUT if Jonno was a "foriegn name" then we wouldnt know anything about him; And we would see in the fight, that he had heart and determination to have-a-go.
Fair play to him, I say....

PS John Dennis would be humongous at 59kgs! :)
