If Switzer was correct in his assessment of you win with Jimmy's and Joe's and not X's and O's and the numbers indicate he is. Then their is a significant correlation with the ranking of recruiting classes and season end's national ranking in football and final fours in MBB, WBB, baseball and softball.
The evaluation of both football and MBB talent is far more accurate than the other sports because of the amount of third party resources committed to evaluating the talent. But there is validity to evaluations in all the sports. For certain the evaluation of talent is not linear hence you have multiple 5*s that fail and many 3*'s that are hits but the projections are far more right than they are wrong. Despite these obvious exceptions recruiting rankings are useful for creating a recruiting baseline for expectations. But the narrower you focus the less useful they become.
If you look at any college sport's final top 10 and then look at the top ten schools in recruiting in their sport the two list are amazingly similar over time. Therefore, I think it is valid to state that you cannot consistently play in Final Four's or the CWS's without consistently having top 10 or better talent. However you cannot acquire talent from recruiting list as you need talent that is compatible with your scheme and approach.
If you look at the schools that have won the WCWS since 2000 (OU-3; Florida, Arizona, UCLA and ASU-2 and Alabama, Cal, Michigan and Washington-1 you would find all of them are consistently listed among the top ten recruiting class list. LSU, Stanford, Georgia, aTm and Tennessee consistenty make these recruiting list and a frequent participants in the WCWS as well.
Below is a detailed analysis of football recruiting that fully documents the validity of recruiting ranking using the star system as an example. The logic of this analysis is applicable to the other sports but the error factor would be greater because the evaluation system is not as through for those sports because demand for their assessments is less. Very through analysis.
