MD feeder school number is miss represented. If MD received all of the students in their feeder, they would/could be larger. But the enrollment in the MD feeder school are drastically down compare to past numbers.
From my own experience, my oldest son's class at had 44 8th grade students. They had 21 boys. 6 went to Memorial, 1 to North, 4 to Central, 2 to Signature, and 8 went to MD. My youngest son class had 11 8th graders and 4 boys in the class. 2 went to MD, 1 went to Reitz, and one went to Signature. On the other hand my daughter's 8th grade class had 12 students and 8 were boys. Once again, 5 went to MD, 2 went to Reitz, and 1 to Signature. Typically, all 8 feeder school feed about a total of 110-125 students into MD. For this purpose, we will say it is a 50/50 split. MD gets about 55-75 boys per year. MD gets if share, but it loses boys to other schools.
You can see when to you drop from a class of 44 students to a feeder school to classes of 12 in ten years, MD does not get as many athletes as they used to. MD must battle cost and Public HS that have great academic (Reitz, Central, North Posey, Gibson Southern, Mt Vernon, and North)
