There is always a few owners from a previous year of a league like this who don't want to come back. Sometimes they will take a season or two off and then want back in. Each season usually has a half dozen or so new owners and dropouts. Thats why a blacklist is difficult, not to mention the secretarial work I would have.
You mention a couple of quarterbacks that I wouldn't be surprised that we actually see in season two. I bet Jurgensen, Moon, maybe Gabrial and so on that might get drafted instead of Baugh, maybe Fouts etc.
