One of the most positive signs this season for Maryland has been the play of Derik Queen, especially against the toughest teams on the Terrapins’ schedule.While Tuesday’s matchup against Saint Francis (Pa.) of the Northeast Conference doesn’t figure to be one of Maryland’s most challenging tests, it does find Queen in peak form.The 6-foot-10 freshman will be a lot for the Red Flash (4-7) to handle when they travel to College Park, Md. to face the Terrapins (8-2).In his last outing on Dec. 8, Queen delivered 26 points and 12 rebounds in Maryland’s 83-78 loss at then-No. 8 Purdue.Last month, Queen scored 24 points in a 78-74 loss to then-No. 15 Marquette and collected 22 points, 11 rebounds and five assists in a 76-75 win over Villanova.With Queen leading the team in scoring (17.5 points) and rebounds (8.7) per game, the Terrapins are vastly improved offensively.But coach Kevin Willard wants to see better work at the defensive end. Maryland surrendered 52 points in the second half against Purdue.”Our half-court defense in the first half was really good,” Willard said. “Our transition defense in the second half was, you know, the crowd got into it. We got a little bit rattled.”
