The reason we use our foot on the hip is to make it harder to "smash" the guard. In other words, getting your weight behind the knee like you showed. The problem is that it is too easy for a good top player to either do that, or use the threat to weave inside the knee and go heavy, like your opponent did in the match. He didnt get the pass, but he did get passed that part of the guard a few times.
The other advantage of having the foot on the hip is in transitions and sweeps. For example, in the omoplata you showed (I think you went to a carni or gogo or something), it's nice to avoid having to deal with the trapped butterfly hook. And if he manages to switch you to the other side (much harder to do at this point), it's still easy to stick in the butterfly for the switch.
Play around with the foot on the hip if you haven't already. It really closes off that side to the guy on top, forcing him to try to go away from the shield, and your arm on his shoulder/head makes that a nightmare. Or, just let me know why you like the foot inside, if you have already been through this.
Thanks Rick!
