As pointed out above, there's obviously no quality control by Pregame over these picks. I am an unpaid, 3rd party (between pregame and the customer) pick grader and as such I would typically only change an egregious, obviously bad line. If a post has a time history showing several major books with a significantly different line at the time of the pick, I'll be glad to regrade it.
It's a shame, but it is what it is.
