I’m really, really happy for him.”RJ Luis collected 19 points and eight rebounds as St. John’s won its eighth straight Big East game, its longest winning streak in league play since it posted eight straight victories from Feb. 1 from March 2, 1992.Luis (17.5), Zuby Ejiofor (14.4) and Richmond (11.9) are averaging double-digit point totals per game for the Red Storm.
