"The other guys just caught lightning in a bottle with a great game"

Rick Pitino's quote is referring to the success of a rival. He is acknowledging that the other group was able to achieve something amazing and unanticipated. He is suggesting that the other group was able to capture something that is challenging to reproduce, like lightning in a bottle. This might indicate that the other group had the ability to develop a fantastic video game that was successful and popular, or that they had the ability to attain a terrific result in a game that was unforeseen. In any case, Rick Pitino is acknowledging the success of the other team and acknowledging that they were able to do something unique. He is also implying that the success of the other group was not something that could be easily replicated.
