First, we will not get to 85 recruited scholarship players for another couple of years, if that.
Second, while I am happy for these kids, there is also a "cold hard reality" reason why Manny needs to give out 85 scholarships. We cannot use the mid-year graduation replacement exception if we are below 85 scholarships.
In short, we have 25 IC slots we can use next year. If we have any guys who graduate in December and leave the team, we can "replace" them with January signees, thus raising our number above 25 (we usually get 1 or 2 extra IC slots this way). But if we are only at 80 scholarships awarded for the year, we can't use the exception.
So it is to Miami's benefit to give the full 85, even to walk-ons.
In addition, scholarships are 1-year renewable. So if we need the scholarship, the walk-ons don't get renewed. Many walk-ons don't even spend all 4 years playing football.
This is good, and there really isn't a downside.
