ATLANTA — Mired in a slump, Rion Brown made himself at home on the road Saturday when Miami’s junior guard came off the bench to score a career-high 22 points and lead the Hurricanes to a 62-49 win at Georgia Tech — once his father’s home. Even without injured center Reggie Johnson, the Hurricanes (10-3, 1-0 Atlantic Coast Conference) had size to spare while outscoring the Yellow Jackets 28-16 in the paint and outrebounding the home team 40-29. Georgia Tech (10-3, 0-1) suffered its first loss in nine games in its new arena.
