A lot of people like to waste bandwidth trying to get across the idea that jiujitsu is split in two areas - street vs sport - when the truth is that jiujitsu is jiujitsu. If you understand it, and grasp the framework and principles, you see it is the same. You can compare it to guitar playing. Someone can play rock guitar, or jazz guitar, or classical guitar, but the fundamentals of guitar playing are the same. It just depends on the music you want to play. The same can be said for BJJ.
Here is a video that takes an in-depth look at how Jiujitsu fundamentals are the same regardless of context. Whether we are are doing sport or street, we need to do the same essential things, and our training can reflect that, and we can train for it all with very few adjustments.
