Hardy was marketed as a KO striker when he had a few KO's over nobodies. He did nothing to cement this reputation in the UFC with his single KO over a collapsed-lung one-dimensional striker in Markham.
I respect that he has spent a lot of time at 10th Planet filling out his skillset and he's not a bad fighter or anything, but his hype seems to me to be mostly about attracting UK fans to the UFC fold... not his actual potential.
His helmet was stifling, it narrowed his vision. And he must see far. His shield was heavy. It threw him off balance. And his target is far away.
