That might be a bit of hindsight, Gonsalves and Gordon were never in the Kirlloff and Lewis territory, but they were both top 100 prospects for multiple years. I don't think the expectation for them was to have Gordon in the minors 7 years after drafting him or Stephen Gonsalves would be put on waivers after 24 MLB innings.
But lets be real both Gordon and Lewis were/are ranked where they are based on their draft position. If either would have been a 3rd rounder or later they would never be ranked as high as they are or were.
The scouting evaluations determine a prospect's initial ranking, and then progress at skill development, and to a lesser extent statistical performance and health, factor in. And of course, where they are drafted is a function of those evaluations.
Gonsalves was a 4th rounder, thought to be a possible steal, but never regarded as a front rotation talent, and early scouting reports detailed his skill deficiencies. He didn't make anyone's Top 100 until he made some progress. Gordon, while lauded for his physical talent, "makeup" and his pedigree, was thought to have, from the outset, a ceiling of "above average" IF with questions about his defense and hit skills.
In actuality, both Gordon and Gonsalves fell off the Top 100 lists pretty quickly, and it's now been awhile since anyone was excited about either of them whatsoever, outside of this board perhaps. Injuries have played a part in that, but I'm guessing their fall from grace is mostly about skills not matching talent.
Gordon could still have a light go on and become a player. But Lewis is in a different category altogether. And Kirilloff was part of a decent draft class, and his hit tool has never been in question. He gets the standard corner OF discount in prospect rankings and is a much more promising prospect than Gonsalves and Gordon ever were. His injuries have suppressed his prospect standing too.
