To deny that there a lot of talented players on the market in the spring is to ignore how many players have come on the market the last few weeks alone,simply due to coaching changes. That has changed in recent years. Now, schools release players without a second thought when their coaches move on. And more coaches are let go than ever before because of the huge contracts and all the pressure to win.
So,that makes spring a big factor in recruiting these days,like it or not.
As far as Basabe not being a typical spring recruit due to his commitment to Siena in the fall...no,that is the point, Basabe is exactly the kind of spring recruit that is ever-increasing due to coaching changes. If Basabe had not chosen to be loyal to Fran,he easily could have been playing in the Big East his past season as a late commitment to St Johns,or Seton Hall, ect.
The other factor in spring recruiting is that late bloomers get a second chance,and often 17yr old kids blossom in that senior year..no shock. It is like the NBA wants to have a 2 year rule for early entry...more time to evaluate kids that are still developing physically and mentally. You can avoid a JR Angle type of situation where you offer a kid as a sophmore and he never gets better.
