The 6-foot-9 forward had a breakthrough junior season with consistently fine and often dominating play at both ends of the court. In leading the No. 3 Gaels (34-3) to the Maryland Interscholastic Athletic Association A Conference and Baltimore Catholic League titles, Smith averaged 17 points, nine rebounds and three blocked shots per game. Offensively, he scored inside, hit 3-pointers and also ran the floor well to finish baskets in transition. On defense, his length and smart positioning made him an imposing threat to block and alter shots. Smith finished with 19 double-doubles, including 28 points, 13 rebounds and four blocked shots in the Gaels' 65-54 win over No. 5 Mount Carmel in the Maryland Interscholastic Athletic Association A Conference championship game. Smith was named Maryland's Gatorade Player of the Year, Baltimore Catholic League's Player of the Year and also its Defensive Player of the Year. "Jalen may have had one of the best seasons ever in the history of Mount Saint Joe basketball. His impact on both ends of the court and level of consistency were big time," Mount Saint Joseph coach Pat Clatchey said. He has a long list of college offers, including Villanova, Notre Dame, Maryland, Florida, Stanford and Virginia.
