Steven is unproven, eh? I don't begrudge you that opinion. He has promised the moon and the stars for years, and only now has he begun to deliver a Wright Brothers flight. I get it. It just doesn't bother me as much as you. I see SKS as only a part of the Wave story. You seem to only want to emphasize SKS and then only his negatives and failures. Fine. They are your nails. Chew away...
I feel the need to ask, at what point will SKS be considered to have delivered sufficiently on his promises by you? What does he have to do?
Regarding nags- see the story of Seabiscuit. Won nothing his first four years, then became the best horse in the country. Good thing his owners didn't turn him into glue.
