Miami Heat. TYLER JOHNSON. D. <i>Stats: 17 MIN, 0-4 FG, 0-1 3FG, 0-0 FT, 3 REB, 1 AST, 1 STL, 0 BLK, 0 TO, 0 PTS</i> Maybe it’s because Henry Walker’s been cold or it was something to do with the specific matchup, but Tyler Johnson replaced Walker in Spo’s nine-man rotation tonight. He couldn’t hit a shot, but he brought his usual hustle and energy. That counts for something.. G
