I kinda agree, but I still get a lot from him. I think Jeff teaches conceptual stuff really well, but doesn't necessarily break it down as well as some (in his videos, at least). So, I like to watch his stuff, and then see how other guys are applying it. My favorite person for this is Ryan Hall, for example.
Also, how you play deep-half changes a lot based on your body type, as well as the body type of the guy on top of you. So, he might be showing you the best way for someone built like Jeff Glover to sweep a stout opponent, while you are way stockier and trying to sweep a far lankier opponent (just random adjectives, I don't know your build obviously). The point is, once you get the moves down, play with them a bit. Change things like angles and grips, and see what works for you. It's impossible to say "do this move exactly like this" for every move in the deep-half, because the position is so complicated. It's like "the guard": everyone does it a little differently.
