1. When one person goes for the takedown, should they ALWAYS have inside control first for a setup? Or can they go for a shot from afar if they are fast?
http://www.thewrestlingtalk.com/videos/VideoID-1124/ This is where the guy doesn't have inside control or anything, but shoots. Is that just for the drill or can you do that during a live match? In other videos, they show setups from inside control.

2. I know how to escape the half when you are on your belly, but what do you do when the opponent rolls you over to your back? I know you can bridge out and roll over, roll over as you are being turned to your back, and peel it off. What is the best way to do it?
