The difference is when you miss on a guy that has only 2 years eligibility left, he's taking away your depth at that position because you have to find another player to build the program from underneath. At least with a true HS signee, or JC with 3 years of eligibility left, if they can't help you right away, you have more time to develop them. Sure, it's always a risk that coaches can miss on any prospect. The natural attrition rate was around 25 percent at one time. But if you are looking at a P5 OL/DL in the portal and he has very little interest, that's a good indicator he is either a bust or a character risk.
