I'll second the Oklahoma drill.

Oklahoma is definitely a favorite. I like the Machine Gun Drill: two lines of players, with one player about 3-4 yds away, facing them. The player points to the first person in either line, and the "machine gun" begins. The "hitters" alternate each time (so both lines & both shoulders of the hitter are going). The coach has to be there to keep them from coming too fast. They are instructed to wait until the hitter is reset, before they come at him.

You can coach proper technique for dipping the shoulder, firing up the forearm, and sheding the "blocker". Great drill especially for LBs.
