Have you looked at the rosters of teams around the country? Many (if not most), including top 25-ish programs, have at least one transfer playing prominent roles. You take this black and white approach that is clearly not accurate -- by no means is it true that the only way to build a good program is to exclusively recruit high school kids. Within our own league, ISU is the obvious example, but there are impact transfers all over the country. It is ridiculously simplistic, and wrong, to act like there is only one way to approach recruiting. Just like it is overly simplistic for people to act like the only way to successfully coach is to be a fiery disciplinarian. People see OU struggle and conclude that if only Lon yelled, cussed, etc., things would be different. Well, how do those people account for Virginia's success? I don't see Tony Bennett show much emotion or rant and rave, yet his team plays as hard as any team in the nation. Recruiting and coaching are no different than anything else in life -- there are a lot of different styles and approaches that can work.
And how is WSU a bad example? It perfectly illustrates why you don't want to end up with more than half your roster in the same class. Their previous teams all had a mix of guys in different classes, including some key JUCO and transfers. That helped them sustain success, because they rarely graduated more than 2 or 3 guys in a given year. But last year, they lost the vast majority of the team in the same graduating class, and that has led directly to their first bad year in a decade.
