No. 4 Duke’s past and future will collide in Tuesday night’s game against Army in West Point, N.Y.The unusual road trip is a sentimental nod to Mike Krzyzewski’s 42 seasons (1980-2022) as head coach at Duke, and his five seasons (1975-80) as head coach at Army and three seasons (1966-69) as a player there.Krzyzewski played for legendary coach Bob Knight at West Point. As a coach, Krzyzewski’s impact on Army basketball likely stretches beyond the humble 73-59 mark he compiled there.Krzyzewski, 78, will be honored with a pregame ceremony on Tuesday.”We started to have conversations about this game about 2 1/2 years ago,” Scheyer said. “To honor all our veterans on Veterans Day — that’s a special thing — and also to honor Coach K, (who’s) going to come on the trip with us.”Two games into his career, Duke freshman forward Cameron Boozer already is making his case as a superstar and will lead the Blue Devils on Tuesday.In this young season, Boozer is averaging 20 points, 10.5 rebounds and 3.5 assists per game, approaching the highest standards of Duke’s lengthy roster of outstanding freshmen.Boozer had 25 points and eight rebounds in Saturday’s 95-54 win over Western Carolina. He hit 4 of 9 shots from 3-point range. Boozer’s twin brother, Cayden, notched 14 points, seven rebounds and five assists in the victory and is averaging 8.0, 5.0 and 3.5, respectively, in two games this year.”Cayden’s first college three was assisted by his brother, and his dad (Duke alum Carlos Boozer) was sitting under the basket,” Duke coach Jon Scheyer said. “Are there times you have to remind yourself just how special this dynamic is? Yeah … that may never happen again.”
