You might be correct! But, ironically, its only because both of you are actually wrong
Turns out D1 as a whole is currently shooting 71.4% from the FT line, which would be 3rd best all time and only 0.3% off the record. Each of the last two seasons have seen a 71.7% FT average.
This season is also the second oldest in the Kenpom database, roughly on par with the 2022 season and trailing only 2023 in terms of total experience.
So it turns out that, recently at least, FT percentage and total player experience have trended quite closely. But they've both moved in the opposite direction than you may have guessed
