Couple other items about Hopkins - not sure how relevant they are.
Hopkins is one of the last districts in the metro (maybe the last) that still uses a junior high model.
K-6 as grade school, 7-9 Jr. High, and 10-12 Sr. High. Pretty much every other school has 9-12 at the high school now, so the coaches are seeing the freshman teams at those schools.
Hopkins also doesn't start youth tackle until 6th grade. the other schools in the LMAA (Edina, Wayzata, Minnetonka, Maple Grove, and St. Louis Park) start in 4th. With the trend toward specialization at younger ages, those Hopkins kids may already be in year-round club sports.
