WASHINGTON — Because of a longstanding Georgetown athletic department policy that forbids freshman athletes from speaking to the media during their first semester of college, talented guard and former Gate City star Mac McClung was unavailable for comment after the Hoyas’ basketball game against Southern Methodist on Saturday. As it turned out, he probably wouldn’t have had much good to say about it anyway. In an 81-73 loss at Capital One Arena, McClung tossed in 13 points on 3-for-8 shooting from the floor.
