With Jakob absent during the 2025 outdoor season, Myers suffered from the 1500/mile reverting to slower burn up races, where strength was less important. This style of racing carried through to the World Champs in Tokyo, which saw him easily knocked out in the heats. Conversely, Laros and Nader cashed in.
I think Myers would have benefitted from faster races where he can showcase his big engine. Inexperience also played into it. In comparison, Jakob almost had a full career by the time he was Myers's current age and was already a confident gold medal winning racer (Euros Outdoors, Indoors, XC). I think Myers has been sheltered or held back somewhat e.g. skipping World Indoors.
If Myers is smart, in 2026 he will control races more and tip the race strategy in his favour. I don't see him concentrating on the 5000m until maybe 2028, he is still so young and has plenty of upside in the 1500m.
