I believe that the players or parents should not get too hung up on the DI,II,or III thing. If the school is the right fit than that is the most important thing. Too many parents feel their kids have got to play D-I ball, and limit their kids options.
Here in Virginia it's pretty much D-I or D-III as D-II is extinct. Some Virginia D-III teams could probably spank some D-I teams. Some States such as Maryland and North Carolina have very good Junior College baseball as well. For reasons unknown Virginia does not have Junior College baseball.
Not every kid wants to go two or three States or more away from home. Some kids that are D-I capable are perfectly happy to be playing on D-III teams in State.
It all comes down to the fit.
