My two cents.....I agree with Varska. Playing a sport for scholarship money is probably not the best use of your time & talents at this point in high school (junior year). BTW...There are scholarships (work study) that you can leverage once in college, and this would be part of your financial aid package. I would suggest you go to College Admissions - SAT - University & College Search Tool
and run through the Financial Aid calculators to see what is possible and what you can afford.
There are so many angles you can look at this. If your primary goal is to get an education, I would stick with that. In my home state (VA), we have a Community College (CC) program that allows you to leverage (with results) that CC experience into one of the main state schools (UVA, VA Tech, JMU, etc) after two years. So you go to CC for two years and then transfer into state school if you meet all the criteria (guaranteed). The benefit of the CC is that it is substantially less $$ than a 4 year school. I would look into a program like this in your home state and call this Plan A. If you were my daughter, I would research the heck out of Plan A first. My understanding is this program is very popular right now given our national economic condition and the escalating cost of Higher Education.
I would then think about playing a sport that you are passionate about, and the sport that presents you with the best chance of scholarship. I would call that Plan B. Keep in mind that you will spend considerable time playing the recruiting "game", playing your sport, and maintaining your studies. It may look good from the outside, but it is really hard work. You haven't played a sport in a while, so it will be even harder. Realistically, it really helps to have someone at home help you with this if you go Plan B.
Next option would be a combination of Plan A and Plan B if you are really passionate about a particular sport. Otherwise work study may be your best way to finance your education.
Those are my initial thoughts. I hope this helps, and I wish you the best of luck.
