I think this discussion is very premature and this class is actually going to have more highly rated guys than any Riley class and the majority of Pelini classes as well (possibly all of them). Frost is already bringing in more talent than previous staffs and he has had very little time to work with.
Here are the number of 5.7 three stars (highest rated 3 star) or higher in the following classes:
2008: 11
2009: 11
2010: 13
2011: 14
2012: 12
2013: 17
2014: 7
2015: 9
2016: 9
2017: 9
2018: 15 (at least 12 of which committed after Frost took over)
2019: 9 (with likely 10 spots left to fill)
Now granted, we want better recruiting than we got under the previous two staffs but things seem to be trending in the right direction, especially considering we haven't played a SINGLE GAME under Frost yet.
The problem with lowering the number to 5.7 three stars, is that you are not comparing that to the other schools. The report that got this conversation all started referenced 4 and 5 star players, not 5.7 I get what you are trying to say, but unless you do that for all the schools you are comparing apples to oranges.
Nebraska had 9 4 star players in the class last year, 6 committed to Frost, 3 to Riley. 9 of 25 is 36%. So far in 2019 there are 3 Rivals 4 stars out of 16 commitments or 25%. So in two years, there are 12 of 41 or 29%. I am sure that if we added the 5.7 3 stars to all the other teams, we would still be in a similar situation as we are now, when comparing Nebraska to other schools.
