Coach Herzog does this sometimes too. I agree that it's a great way help chain together different series'. I like his analogy of a hallway with a bunch of doors on each side. The goal is to go down the hallway but if a door opens, know whether and how to take it. I assume that's why sometimes we work on transitions down a path (e.g. MC -> NY -> Chill dog -> kung fu move -> jiu claw -> omaplata) and other times we work several options from the same position (e.g. snap roll to the back; RNC, Goon, Chevy to twister, etc.). The "transition down a path" ones are the main hallways and the "same position" ones are the door options. Put them together and you have quite an arsenal. I think... Coach?
