Saw many "two-way" hs players never make it to their dream school or any school at all. Usually it is a direct result of the player not understanding how good the competition really is at their dream school.
If you want to be a professional at something, the common thought process is that you must put in 10,000 hours in training. By the way, the word "training" in the above sentence is very encompassing just for ONE position.
There is a growing trend out there where players are being home schooled, held back a 1 year / 2 years or going to HS but not playing baseball. Why? They understand the 10,000 hour thing...They also understand grades are important. My son had the privledge of playing with many of these guys and they all went to their dream schools or were drafted out of HS.
Soar with your strengths....if you are not being seriously recognized for a second position by HS do you want to risk becoming average in your strenght position due to reduced training / development time? Trust me there are guys out there that are hoping you want to be a two way guy....it increases their odds of taking your roster spot!
