Right now this is all on the back of the coaches selling their vision. They have improved so much that all meets have been moved from "The Barn"(seats 500 that's the 1931 building) to the RAC drawing in around the 3,000 range for matches. Those are now selling points the coaches can use for recruiting, couple that with the new training facility, increased OOS scholarship funding(that's roughly an extra stud recruit a year) and top 4 in the B1G year in year out is not an unrealistic goal anymore.
The SK wrestling club is still in it's infancy and is beginning to bring in top flight coaches. Those guys do a tremendous job with starting that sucker from scratch and now with the partnership with Princeton and the backing of some huge donors it's about to explode. IMO the top 10 finishes are just the start as there are so many more structural and financial improvements yet to be accomplished.
