Was Odin always the main nordic god? Perhaps, but not the most often worshipped. The folk of Scandinavia have seen it fit to make centric that who represented best the home's landscape and biome along with occupation and history. For example, Thor was mainly worshipped by builders/ farmers as he made their patron god and also had a prevalence in rocky areas (Western Norway, Sweden, one of his holy cities Paderborn and oak as his symbol), Freyja and Freyr in forests and farmlands, Tyr the honor, sword and sky god worshipped mainly by the high ranking (mainly in Denmark and Norway where the sky is most prevalent in sight and trees spaced out, tree symbol being the ash) What about the Nordic Bronze Age gods? Older than the one-eyed king of gods might be what seems like Proto-Tyr (etymology: Tiwaz), whose recurring motiffs (one arm, twin, blade-wielding) dominate the Scandinavian Bronze Age artworks. He represents the existence of man's spirit which is immortal, unlike the body which rots but that spirit may reincarnate, thus rebirth being the main belief of Heathenry (one symbol of reincarnation from this period is the Sun Wheel, a "flagship" symbol of Teutonic Paganism, also by the way the word "Teutonic" stems from "Tiwaz").
