What Jonny Ninja says.
Haye is sharp, well-spoken & meedja-friendly. He often gives the impression of being a bit too media friendly, empty soundbites delivered for ratings. He's also incredibly full of himself (as someone who is rather good at beating people up & who is extremely attractive to the opposite sex, I for one cannot imagine what led him to this estimation of his self-worth). He has a tendency to over-talk his own performances & chances.
All the above these things mean that he gets right under the skin of a certain personality type. Normally, the chest-puffing gun-stroking wingnut wannabe-John Waynes. I mean, it's natural & correct to think Haye's a gobshite, but people like the OP simply don't stop there, they'll tell you that he's not talented or that he's a "fraud".
Downplaying the Chisora result (which is still & by far the best fucking result anyone's ever had with Del Boy, still, which includes a distance fight with Vit Klit, two tussles with Fury, twelve rounds with Pulev & a razor thin loss to Whyte) tells you all you need to know about the OP's opinion of Haye, which is obviously weirdly biased.
PS: Yes, his comeback opposition has been laughable. No question. But the revisionist bullshit the OP indulges in is just weird.
