Keep your name in front of the coaches by continually updating them on anything new that has happened, a big tournament win, an award, and academic achievement, etc. For example, show an interest in the coach's life. A Christmas card to the coach and his family or a letter of congratulations if his team has a big win helps to further plant your name in the coach's mind and it is quite often these seemingly insignificant details that can sway a coach's decision. Also, try to be seen as much as possible. Play as many tournaments as possible and attend college camps.
Many college coaches conduct summer camps.
Go to these, get to know the coach and vice versa. The better you can get to know the college coaches, and they you, the better the chance of staying in their minds when the time comes for them to decide who they'll offer their scholarships to. I hope that these last two columns will serve as a good start to your quest for a college scholarship. There are, however, many more elements you will need to be familiar with in order to complete the task thoroughly and properly. Too many, in fact, for this space to adequately address.
