One of the things we have altered recently is the control positions when we put someone on the ground. This came from a number of factors one being an article I read in Black Belt Magazine dealing with the differences in Classical Jujitsu and MMA. Basically MMA is a one on one fight so there are positions that give the best control when no one else can join in. On the other hand classical Jujitsu was designed for the battle field where you always had to be aware that someone else could attack you at any time.
this is good stuff Rick and I agree , I try and go for a knee ride over a sidemount etc , and open guard over closed guard if possible .. etc etc , I like to be able to transition up and down us much as you can forwards backwards etc ... I dont mind takedowns throws that include me going down , but they have to have me in a position where I`m transitioning through the move and not stuck there .
but i`m just a novice at the ground , these are only best case scenarios
