IMO, in many cases the individual wrestler has the much greater part to play in how their career turns out. Most top tier programs have very good coaching. The difference makers for me with regard to coaching are more mental and philosophical in nature rather than techniques. For example, many past Iowa wrestlers say that there is too much emphasis on winning rather than just becoming a better wrestler. Adds too much pressure. The other difference maker is a thoughtful approach to the season so that the wrestlers are peaking in March and not February. Lastly, individual scouting of opponents during nationals has helped PSU tremendously in "last matches won".
As for recruiting rankings, I think the further back you go, the more the rankings skewed towards overvaluing a larger class rather than a small quality class.
