I think it is likely multi-faceted...
Conference opponents of Stevenson, Gurnee Warren, Lake Zurich, Libertyville, and Lake Forest do not make things easy. Stevenson & Warren double the size of Mundelein and consistently field good teams. LZ, Libertyville, and LF, while comparable in size, have had no shortage of good teams in recent years.
Carmel certainly can't help matters either - I don't know of any publicly available statistics, but I'd venture to guess they pull a good # of their enrollment from Mundelein school district. I'd agree with previous poster, based upon academic metrics, parent's are more likely to get bang for their buck coming out of the Mundelein school district vs Libertyville.
Culturally MHS is ~40% Hispanic. While certainly not an absolute inhibitor to success, I'd imagine in comparison to many of their conference rivals, many students at the school may not grow up in a home/culture that puts a significant athletic emphasis on football compared to alternative sports.
