National Championships The Irish were awarded two
Helms Athletic Foundation National Championships. •
1926–27 Helms Foundation National Champions •
1935–36 Helms Foundation National Champions Upsets of Number 1's and unbeatens The wins include several wins over the defending
NCAA Tournament Champion. Both wins over UCLA were in seasons immediately following UCLA claiming the NCAA Championship with the 1971 win coming over a team that would be the eventual tournament champion. The 1954 win in the NCAA tournament over Indiana prevented IU from back-to-back national titles after claiming the 1953 NCAA Tournament Title. The 1978 win over Marquette was another instance of the Irish defeating the defending national champion. The 1948 win over Kentucky saw the Irish defeat the eventual Tournament champion who would go on to win both the 1948 and 1949 titles. The 1948 win over NYU was a victory over the eventual
NIT runner-up, in a time when the prestige of the NIT tournament rivaled that of the NCAA tournament. Also of note is that the 2005 win over Boston College and the 2012 win over Syracuse saw 20–0 teams traveling to South Bend and leaving with their first loss of the season. Boston College, in its final year as a member of the Big East, set the record for most consecutive wins by a Big East team to start a season. The 2012 Syracuse team began the game against the Irish with the goal of breaking Boston College's record. As in 2005, the Irish defeated Syracuse and cemented their place as the streak stopper. ;Notes ==Coaches==
