The average college baseball schollie is worth 6 grand and is a 32% ride. If you increase that value by 10%, it still is peanuts.
In the low partial sports like baseball, getting a “scholarship” has almost nothing to do with economics. It is primarily about pride – “Did you hear that Johnny got a scholarship to play baseball at State U!!” But the proud parents usually don’t mention that Johnny’s scholarship is worth like 500 bucks as a freshman.
