Yes, Marshall-Walker was the one I couldn’t remember.
From what I understand from that era it was for budgetary reasons as well as competitive reasons. None of the city schools were lighting the world on fire in the late 70's going into the 80's. It existed from 1979-1985 and then they broke apart again.
Marshall-Walker split and Maggie Walker became a Governor's School, John Marshall had early success from 1986-1993.
Jefferson-Huguenot-Wythe split. Huguenot turned a corner when Richard McFee took over in 1988 but from 86-87 they weren't much of anything before that. George Wythe had some moderate success before they fell into decades of despair and now go by the name Richmond High School of the Arts. TJ struggled mightily until the mid-2010's when Chad Hornik revitalized that program.
Armstrong-Kennedy split and neither team had much success afterwards. Armstrong made the playoffs in 1992 and Kennedy never did after the fact. Then they closed Armstrong in 2003, merged the schools into Kennedy and renamed the school.
Since 2013 the City has seen a revitalization... TJ, Huguenot and Armstrong are the jewels of the city. John Marshall had moderate success under Coach Sims. Wythe became Richmond, Richmond is getting a new school... not sure if that will make a difference on the field.
What I would love to see personally would be the merger of TJ and John Marshall. The City of Richmond does not really take care of their schools like they should. I think having 4 high schools in the city makes a lot more sense than 5.
What I would like to see as well is the those who clamored for the name change to Armstrong-Kennedy to foot the bill through fundraising efforts. It should not be up to the City of Richmond to foot a $100K bill for a name change. That money can be spent for so many other resources the kids in the City of Richmond could use.
