Full rides for soccer are rare, unless on national team. Soccer programs are only allowed 11-12 full per NCAA, thus, easy calculation if you have 24-28 players. Usually max would be 1/2 then offset by academic scholarships. The whole process for the player looking to play at the next level takes a great deal of effort, a little luck, and a lot of PR. Would gladly help or assist if anybody is looking for more details or assistance.
