This is another one of my favorite combo’s from the guard.  The thing I like about this combo is the ease in which one move blends into another..

As a side note I end this series a little differently than shown in this video.  After I’ve completed the back roll sweep I like to spin backward and end up in the S-mount. In the video you see him turn towards the opponent and end up in side control.  Theres nothing wrong with ending the sequence that way, I just find it easier to flow from the roll to S-mount.  Also, if your opponent is a big guy he can sometimes muscle you off if you try turning into him for the side mount….
