Matt, I have been drilling the passing concepts we covered. I have been drilling combat base a lot, and isolating it against resistance as you suggested. You emphasized T-Rex arms (elbows in tight, don't reach out). My question is that my partners are shrimping away and going to their knees lately. Do you use your hands ever to control/impeded their hip movement? or is it just a lag in timing on my part? I know that if they shrimp, there is an opportunity to knee slide pass but do you ever try to control them with your arms/hands from combat base? Thanks.
