If you are an unsigned senior, it is by no means too late! What does have to happen is a surge of communication from you to a wider range of schools. You will have to honestly evaluate yourself as a player and identify if you need to sell your abilities to a school in a smaller division. Many smaller schools are still recruiting seniors at this point and will be happy that a recruit is contacting them. Remember, not all schools and have large recruiting budget and it may take time and energy on your part to find the school that is looking for you. Keep looking and sending your information out.
