There's nothing really wrong with the list IMO. Beyond the obvious top 2... everyone else is either at a high enough level that you know what youre getting, or low enough that there's still such a wide variety of outcomes that you wouldn't really expect impact players. They do mention Nunez at the bottom of the article in their "Power-Over-Hit Fliers"
Rainer Nunez, 1B - Nunez is a huge-framed 3B/1B who is almost certain to be first base-only at maturity. He’s kept his K rates under control so far, but his righty-hitting first base profile means he has a high bar to clear.
Zach Britton, OF - Britton has above-average bat speed but a 40 hit tool.
Sebastian Espino, 3B - Espino has a 70 frame and a great-looking swing, but he has no feel for the barrel.
Reallistically, Nunez has a profile that every team has like 5 of in the minors so its kinda hard to be excited about him.
