The team ranked first at the end of the season, Ignis Varese, was crowned champion (earning the single spot in the European Champions Cup) whilst the two lowest ranked teams, Splugen Brau Gorizia and Brill Cagliari, were relegated to the Serie A. Ignis Varese won their second consecutive league title, fourth overall.

[1][3] The defending champions had named Aleksandar Nikolić as coach and reinforced a squad already containing Raga, Dino Meneghin, Aldo Ossola and Ottorino Flaborea with former league top-scorer Paolo Vittori, Simmenthal had two arrivals (including Renzo Bariviera) for two departures, with the form of key duo Massimo Masini and Jim Tillman cause for concern, All'Onesta' were counting on American pair Gennari and Joe Isaac, Virtus Bologna - led by captain Dado Lombardi and 1969 NBA draft fourth-pick Terry Driscoll with recent Italy coach Nello Paratore at the helm - were seen as the dark horse for the title, with Napoli – minus Vittori – described as having a competitive but aging squad.

[2] After nine straight wins to open the season, Varese was undone 73-76 after one overtime by Simmenthal Milano on 11 January 1970, allowing the Milanese to close the gap between the two front runners to two points.

[4] The Ignis-sponsored club lost only once more, an 80-88 defeat to Snaidero Udine on 22 March 1970, right before playing Real Madrid in the European Champions Cup.

[3] Splugen Brau Gorizia, the other promoted side that season besides Cagliari, had seen their relegation confirmed the previous round,[6] despite their player Elnardo Webster leading the league in scoring with 593 points (26.9 per game) to Raga's 558 (25.4 pg).
