Mike Mayock has a great explanation of drills and times for those who aren't as versed in the combine. Click on workout drills then on the drill you are in question about. He will also give you good times/measurements to compare with. It is pretty interesting stuff comparing the numbers of some players to how well they actually performed on field. I also noticed quite a few titans being represented in the videos; Chris Johnson being the obvious one, but also Britt, and I believe Javon Ringer.
