I think the point is being missed repeatedly here...
It's as simple as face value.
JD Smith makes amazing knives. Better than most who have been on the show, period. In his own shop, or at the university.
He got beat at a game. Partly due to his own inattention, partly because he was out of his comfort zone.
I can attest absolutely to how hard it is to retain the information that Will is speaking in the moment. I felt lucky at one point that we had to do another take, because the size requirement he'd just uttered went in one ear and out the other. You get wrapped up in your game plan, and it is hard to focus correctly.
For that matter, the second time I was on the show, Burt Foster got cut on the first round. I bet privately all of us thought he'd likely win. I know I did.
It's a game, luck is a big factor, coolness under pressure is huge, focus is key, and in the end, it's still Any Given Sunday.
What I like to think, is that for many of the smiths, it serves merely as an introduction to the public. The viewer, if sufficiently interested in the craft, is then free to seek out more information about the work that smith is capable of given normal working conditions.
