We took another step in my house, by the way. This is my house, coach Patrick Ewing, the former New York Knicks star, said in a postgame television interview. Its a great win. Huge win. We played against the Cadillac, the Bentley, whatever you want to call them, of the Big East the class of the Big East. And once upon a time that was us. But we took a huge step to be able to knock them off. . . Harris led the way with 18 points and drew a foul on on Jeremiah Robinson-Earl driving to the basket with 4. 7 seconds left and the Hoyas down one. . . Harris rattled in the first and swished the second to make Georgetown 23 of 23 from the line, the first time a team has shot 100% on at least 20 attempts in the Big East Tournament. . . With no timeouts left, Caleb Daniels rushed up court and got off a long 3-pointer in traffic for Villanova, but it missed badly.

The quarterfinal day at the Garden is often the best of the Big East Tournament. The marathon quadruple-header keeps MSG buzzing from noon to midnight. Not this year. . . With COVID-19 restrictions still in place, the Garden was mostly empty for an old-school Big East matchup between Wildcats and Hoyas. Ewings booming voice echoed through the rafters. Rebound! Rebound! he shouted after just about every Villanova shot went up. . . Each quarterfinal team was given 100 tickets to Thursdays games. There was maybe a few dozen in the stands for the noon tipoff. A Lets Go Nova! chant didnt last long or find many takers. . . BIG PICTURE. . Georgetown. The Hoyas, who are 7-4 after a COVID-19 pause, won a Big East Tournament game for the first time since 2016 and avoided a three-game sweep by Villanova. . . Villanova.

The sophomore contributed three points, five rebounds and four assists. Villanova did have guard Justin Moore left ankle available after coach Jay Wright said earlier that it might take a miracle for the teams third-leading scorer to play in the Big East Tournament.
