Everything BaseballHQ publishes is direct marketing tactics to improve their subscriptions.
As a marketing professional who has written sales letters, and managed many campaigns, this "article" follows sales-letter techniques to a T.
Get their attention with a catchy headline, state something controversial/scary/bizarre to arouse interest, educate about a problem, offer a piece of the solution, and then show where to get the complete package (paid subscription).
This isn't necessary a bad thing. But when somebody is obviously marketing to you, it puts a lot of the information they are providing into a cloud of "is this information real/accurate, or are numbers, statements, etc. being exaggerated with the intent to sell subscriptions?"
This is why I don't bother with baseballHQ.
On that note, I've been doing a similar tactic described in the article for years. I use my favorite projections for hitters & pitchers, I run the dollar values, but then I go over each position, look up every guy, and then manually edit the dollar values based on my "Human" research/intervention.
e.g. if you think a guy is better than his projection, you give him a bump depending on how much better you think he is. If you think somebody is worse you shave off some dollars from his value.
