In ball games, individuals collaborate to enhance their team's performance by sharing images and ideas that have not been verbalized. One of a coach's roles is to ascertain whether players share a common understanding of their team's images so as to devise tactics. Accordingly, this study aimed to verify the hypothesis that sharing images such as tacit knowledge that has not been verbalized occurs in collective interaction when utterances increase substantially during problem-solving. The participants were 13 male university handball players whose teams were championship contenders in Japan. A mixed methods research design was employed. Scenes in which two groups engaged in problem-solving were recorded and data of each participant's utterances were obtained. The utterances were analyzed quantitatively by employing Smirnoff-Grubbs and the time periods including those with a substantial number of utterances were identified. What happened during the identified time periods verified as outliers including the high frequency utterances were analyzed qualitatively by employing consensual qualitative analysis. Finally, the results of the consensual qualitative analysis were used to examine statistically to determine whether specific events occurred during times of extreme high frequency utterances. The exact binomial test was used to determine the 95% confidence interval of the population ratio and the effect size (g) of the mother ratio (0.05) to determine whether non-verbalized images such as tacit knowledge were being shared among members. Of the 26 time periods, 22 were supported the hypothesis. Of the time periods with extremely high utterances, the population ratio of the time periods supporting the hypothesis was 0.846 (CI = 0.681–1.00, g = 0.80). The results revealed that tacit image sharing occurred when there were a substantial number of utterances. This study demonstrated the possibility that sharing images that have not been verbalized occurs in collective interaction when there is a hotspot of utterances.
