BIG STONE GAP — Union’s Justin Falin must like waiting until the end of games to show his defensive prowess. Falin had the game-sealing block with less than 10 seconds left to preserve the Bears’ 64-59 win over Lee in their Mountain 7 District tournament opening-round game Monday night. “On that possession, I was thinking that I was going to need to step up my defense because my man had slipped by me a couple of possessions before and scored,” Falin said.
