Could it be possible that "Wheel"'s contracts still keep stations from scheduling it before 5 p.m. (the clause put in to protect the network daytime version 25 years ago)?
Another thing about the situation in syndication is that there's no room for new first-run shows between 5 and 8 p.m. (7 p.m. in Central and Mountain)--barring any surprises, "Wheel," "J!", "ET," "Insider," "Access" and "Extra" are going to be in those time slots for years to come. And the Fox/MyTV/CW/pure indie stations, despite some murmurs, are pretty much sticking to sitcom reruns in that time slot, except for "TMZ," local news and in Chicago "WWTBAM." No real push to develop new programming in an instance like this.
As for "DOND," it's the top-rated new series in syndication and just barely out of the Top 20, so I would guess that it's going to a second season.
