It isn't "negativity" at all. It's just an acknowledgement of the history of the quality of players you're typically going to find at the 4th spot in the draft, after the top 3 prospects get selected.
Below is that history, going back to the 1970's. There are some really good players that have been available at 4, and even a few legitimate superstars, but usually you're looking at players who fit into a tier below the eventual superstars. Yes, every draft has a player or two who massively overperforms their draft position. Guys like Jokic and Giannis are exceptional in that nobody predicted their ascension to MVP-worthy status. In other words, you can't know who those players are going to be when you're picking anywhere in the draft, so that doesn't factor into the calculus when you're picking at the top. You can't worry about whether or not a guy who is projected to go 15th or 25th or 35th might become a future MVP. You can only work with the data you have, and here's what GM's did with the data they had at the time of selecting 4th:
