The Crack Back Block
This block is used primarily by the ends when they are blocking an inside linebacker. It can also be used by anyone who might be blocking directly in front of the ball carrier.
Approach:
1. Release from line of scrimmage as quickly as possible and run straight at linebacker.
2. Aim slightly above the knees of the linebacker.
3. Get within a yard and a half before going into block.
Contact:
1. Throw outside arm with a quick, jerky motion in front of linebacker. This quick motion will cause the head and shoulder to get in front of defensive man.
