One can red shirt for a number of reasons (academics, maturity, scholarship limits, etc)...there are advantages to red shirting as long as that particular player is in the mix for the years ahead...if they redshirt and are eligible to play they lose two of their ten semesters...NAIA allows 10 semesters to play 8...we red shirted two players last year at NAIA level, one which was due to grades and the other was going to be a five year student and I wanted time to get him comfortable with the college life and expectations!
