Last season, Marshall shot worse than 40% on FGs in 40% of their Nov./Dec. games, compared to only 10% of the time in their regular season games in Jan.-Mar. And they didn't shoot above 50% on FGs in their Nov./Dec. games at all, compared to 16% of the time in the Jan.-Mar.
For 3-point %, they shot better than 30% in only 40% of their Nov./Dec. games, compared to 84% of their games in Jan.-Mar.
For fouls, they committed less than 20 fouls only once (10%) in their Nov./Dec. games, compared to 63% of the time in their Jan.-Mar. games.
For offensive rebounds, they got 20 or more zero times in their Nov./Dec. games, compared to 21% of the time in their Jan.-Mar. games.
For steals, they got 10 or more in 60% of their Nov./Dec. games, compared to 80% of their Jan.-Mar. games.
I think all of these are pretty good indicators of Kim's team getting increasingly comfortable shooting at pace, pressing without fouling, and going for offensive boards.
