You are mixing up the plays. There was 11:20 left in the second quarter when Hardy took Keyonte out. It didn't happen after a turnover, it happened after a made free throw by Clarkson. Keyonte had all the time in the world to find his man, but he got completely lost. He wasn't doing ok at that point, he was clearly distracted after a couple of easy turnovers he had. It was an easy decison to take him out at that point. Fortunately he improved his play in the second half.
Overall outside of Sexton, the guard play was really tough to watch. Dunn offered nothing offensively, although he played excellent defence against Maxey. Clarkson had a perfect display of all his bad habits. Ochai offers zero threat offensively.
Collins, Lauri and Sexton were feasting today. Collin got past his man at will and after that there was absolutely zero rim protection ahead.
