In this clip? ie bringing one foot back to generate more force, using the other leg to block the knee.

His reasoning makes a lot of sense. Just curious to hear from those who have switched to this method from a more traditional one. How is it working for you?
Did u always do it this way or was it a recent change? Notice a big improvement?
I started noticing a big improvement when I started doing it his way. Never saw those details anywhere else. 
I do the hip bump a little different but I feel it is the most powerful sweep available. It´s more like a punch than a sweep:

Relevant to my interests
nope i don't
Can someone link it please..? 
Ryan is an EXCELLENT instructor.
Just watched it again, and I need to amend my statement; I do reposition my foot back like a sprinter to drive forward, but I do not usually drop my leg to block his leg. It makes sense in principle, but it just doesn't feel comfortable in real time against resistance to me.
Yes, but I rarely use this sweep anymore. I actually like using it on people much bigger than me. More mass trying to posture => more momentum.
Can't see these on my ipad, so ttt for later

^^^ Ipad doens't show youtube vids. Or is it just the sites format of them on this site? Would links help to the youtube vids instead?
Ya, I could click on a hyperlink. I can't even cut and paste here though. I can watch YouTube through my browser on iPad.

yeah, that is the part I was wondering about. just messing around without a partner, the driving foot feels pretty natural, but the blocking leg does feel a bit weird.
it is interesting, when you think about it, the driving foot seems like such an obvious adjustment. yet, when i was going through a hip bump adjustment phase recently, and watching every vid online i could find, none mentioned that.

Zero1's verision of Himp Bump Sweep

Thank you kindly
I do a similar version to this. I try to emphasize the bridging motion and the "punch"with the hip. I think I heard Shawn Williams call it an "up and over " sweep while doing commentary for the worlds and I started to re-think the variation I'd learned. I find if I think of it as a bridge with the top hip and THEN a step up into the armpit (two separate movements) rather than a large generalized motion (which causes counter rotational weakness in the sweepers body) I have a higher degree of success. Hope that makes sense.
I don't focus on moving the driving foot so much as I try to bridge toward a direction (10 o clock if I'm sweeping to my left) that makes my top leg able to drive with strength.

never do the hip bump and i should start practicing it..
up!
No. I trap their hips with the leg Ryan traps their leg with. It's a detail that came from a Kron seminar a few years back. I wouldn't be opposed to playing with Ryan's method either, I suppose. It looks like it might accomplish the same goal in a different manner.
What do y'all think about zero1's variation?
