No, because Gable did stockpile the nation's top high school recruits. I'll make my points in hoping we'll come to a general agreement but I highly doubt it.
1) In terms of Royce Alger not being a top ranked recruit it's a failure of the wrestling media at that time. It's unfair to cast total blame on wrestling media during that era due to them not having the resources that Flo, @Husker_Duetc benefit from in this modern era. By any metric, a 3x Iowa state champ and JR national title winner is a top 10 recruit.
2) You're conveniently omitting or do not know that for years Gable gave extra scholarships. Above the allotted amount allowed by the NCAA's which led to him eventually being sanctioned. To be fair, other Big 10 schools were also doing it but Iowa wrestling egregiously went over the allowed allotment which was proven in a report I will provide for you. Yes, Gable was stockpiling wrestlers. https://web3.ncaa.org/lsdbi/search/miCaseView/report?id=101820 I dont blame Gable for doing this but he was gaming the system. AND he stockpiled wrestlers
