The highlight of Ireland's coaching career occurred in 1963, when he guided the Loyola Ramblers to the national collegiate championship. Ireland's team, led by
Jerry Harkness and
Les Hunter, compiled a 23–2 regular season record and finished first in the country in scoring, averaging 93.9 points per game. They defeated
Tennessee Tech 111–42 in the first round of the NCAA tournament, which is still the largest margin of victory in an NCAA tournament game. After victories over
Mississippi State,
Illinois and
Duke, the Ramblers reached the
finals, where they faced two-time defending champion
Cincinnati. Loyola trailed Cincinnati 45-30 with 13:56 left in the game, but the Ramblers rallied to force an
overtime session with pressing defense and a last-minute jump shot by Harkness. In overtime, they won the game 60–58 with a last-second tip-in by
Vic Rouse. Loyola remains the only school in the state of
Illinois to have won an NCAA Division I basketball championship. The 1963 Loyola team also broke racial barriers by being the first NCAA Division I team to have four African-American players in the everyday lineup. Over twenty years later, Ireland reflected on the team, calling them "An extraordinary group of young men. All intelligent, all willing, all good at what they did. They were not great players, but they were a great team." On July 11, 2013, surviving members of Loyola's team were honored by President
Barack Obama at the
White House to celebrate the 50th anniversary of the school's championship. Ireland was represented at the Oval Office ceremony by his daughter, Judy van Dyck, and by Loyola's current head coach,
Porter Moser. ==Later career==
