St. John’s coach Rick Pitino only saw glimpses of RJ Luis Jr.’s capabilities last year because of a shin injury that cost him 10 games and persisted through the season.This season, Luis is among the major reasons for St. John’s getting off to a hot start in Big East play.The swingman attempts to produce another strong showing Tuesday night when the Red Storm put their unbeaten home record on the line against improving Georgetown in New York.Luis was named Big East Player of the Week after averaging 24 points in the Red Storm’s 10-point win at Xavier and an 80-68 home victory over Villanova on Saturday. He is scoring 17.4 points per game after getting 30 in his third straight double-double on Saturday and is tied with Xavier’s Zach Freemantle as the fourth-best scorer in the Big East.Luis’ big performance helped the Red Storm (14-3, 5-1) improve to 11-0 at home and continued their best start to conference play since the 2000-01 team also started 5-1.”He’s physically stronger than what he was,” Pitino said after Luis scored 23 points in the second half. “He has — and this is a good thing, it’s not a selfish thing — he has an incredible desire to score.”Luis produced his big game after Deivon Smith injured his right shoulder in the first half and was unable to finish the game after trying to briefly play through it in the second. He is day-to-day with a sprained right shoulder and could play Tuesday.
