Jamarii Thomas, a senior transfer from Norfolk State, had 19 points and swished 4 of 5 shots from behind the arc.”Thomas got some good, clean looks,” Paris said. “It was good to see those guys make their shots. Hopefully it gets those guys going in the right direction.”On the season, the Gamecocks are making 7.8 3-pointers per game and shooting 32.5 percent from deep. Senior guard Jacobi Wright makes a team-best 1.8 3-pointers per game and shoots 37.5 percent from behind the arc.

And despite an undefeated record so far for the Musketeers, third-year coach Sean Miller is worried about his players developing bad habits.
