Are you having issues blocking bucksweep effectively? If this is the case, down sweep may have the same issues with the blocking.
Regardless, one of the things that we do is have the fullback cutback towards the center. The cutback helps freeze those backers. That freeze is essential, because you don't have the backside guard pulling through the hole. You don't want to ride the ball too long either. Once the FB is even with the QB, the QB should pull out. If you take too long with the ride, the QB won't have a chance to give to the HB. The other thing is you want the hand off to be done with the QB's back to the defense to hide whether is handing the ball off or faking a hand off. If you sacrifice anything to make the ball time up better, it's the where the QB hands off to the HB. He may expose the ball a little. Sacrificing that is better than sacrificing the ride to the FB or not having the FB cuback.
Good luck,
