Prepster holds the key. The math says that 43% is the average if fully funded...11.7/27=43.333. Then you can throw in your variables of position on field, pitcher, catcher and whether there is any money that is eligible to be combined. My son is an INF. If he gets over 43% from a school, I consider it a good offer based on his role on the team and not being a pitcher. Some schools can then add need-based or academic money to increase the overall offer. Full cost of attendance athletic scholarships in D1 are rare and those players (likely pitchers) may not see college.
IMHO...
