The key to winning big in Men's College Soccer is to bring in foreign students who didn't advance through their home nation's Academy system.
Basically you can recruit foreign kids who were "raised" by professional soccer teams overseas. These academy's are like prep schools for kids, and they train and mix in school work, live on site, etc. If they aren't good enough to sign a contract and play as a professional (around 17-19 yrs old) then some of them, get offered scholarships to attend college and play soccer in the USA. Get a college degree to have a non-soccer career, and get a 2nd chance at making it to the pros.
-A large % of Clemson's team were foreign kids...think of them as like High A baseball players.
-Stanford, who won the title, was an anomaly, in that they had mainly USA born kids on their team. This probably isn't something Pitt can do, since the local soccer talent in northeast, isn't as good as the west coast.
With Pitt's international student base, they probably could field a competitive team in a very short amount of time, if they invest the recruiting $ to go abroad.
