Great quiz! Just a formatting suggestion: there's no need to specify Hartford for the Whalers, Quebec for the Nordiques, Minnesota for the North Stars, or Atlanta for the Thrashers, since those names weren't used by any other city.
Also, the quiz could be updated: Ovechkin has done it three more times, and Leon Draisaitl joins the list.
