Right, in sport jits you do not have to worry about strikes, but you can still use that same entry. The other thing to be cognizant of, is once you are behind them, if it's self-defense or mma, be sure to pin your head to their back/shoulders so the loose arm doesn't fire a huge elbow to your face when you are behind them with the 2-on-1! It's easy to forget. Nobody wants a broken nose :)
