It all depends on the sport. In football you have to play through your junior year. In basketball you have to play one year now. In baseball you don't have to play at all.
college football is when you are in college and pro football is when you are out of college and also in pro football you get paid but not college football. you can get into pro by being a college player and getting drafted into pro.
