Here are some things to consider...
1. Spaz's first full class uses up their five years in time for the new coach's first full class. They were originally 21 scholarships. Because some played as true freshman, their churn will be up even faster. But 21 is still a close enough place holder for a baseline for the class. For purposes of this exercise, call the 21 spots Class 1 for the new coach.
2. Spaz's second full class was 23 scholarships. By the same churn rate, every player from this class should open up a recruiting slot in our new coach's second full class. For purposes of this exercise, call the 23 spots Class 2 for the new coach.
3. Spaz has underrecruited each year and backfilled with scholarships to walkons. Fortunately most of those walkons were and are upper classmen. Right now there are four scholarships that fall into this category. Those extra spots will probably be used in this transitional class, but even if they are spread out, that still provide plenty of flexibility for the new coach.
4. A coaching change will mean accelerated attrition. This number is less predictable put on average BC loses five players over the course of a football season to some sort of attrition (permanent injury, transfer out or kicked off of the team). Assuming we get to six annually for the first two years (because of the coaching change), that once again gives the new coach plenty of flexibility to shape his recruiting classes.
5. The NCAA allows for 85 scholarships for football and only 25 at most per recruiting class.
6. According to the recruiting sites, BC plans on keeping this Transitional Class small and will only add a few more players. For purposes of this exercise, estimate it at 21 commitments.
Transitional Class: 21 commitments
Class 1: 21 commitments
Class 2: 23 commitments
Walkons graduating out of our system: 4
Estimated attrition over the first three seasons: 18
Even in the worst case scenario where our new coach comes in and dislikes nearly all of Spaz's incoming recruits, this one class won't be a long-term issue. And even if someone like Marquis Little is lacking ACC talent, he is just one player. At worst all of these recruits in the transitional class are just depth and warm bodies. By Year 3 more than half of the players on the roster will be the new coach's. If he's aggressive in his roster management, he could have as many as 50 players in his first two full classes. That's a lot of talent and a reminder of how quickly rosters can turn in college football.
I know that the classes don't line up perfectly as they graduate but the point of this was to demonstrate how the rosters churn and anticipate the flexibility the new coach should have. We will be young in his third year, but we will be his team.
