1. Lack of total effort - trying to save yourself for the fourth quarter. By that time, it doesn't matter.

2. Guessing - not playing what you see because you "think" they are going to do something else.

3. Trying to make a tackle or big play without first defeating primary blocker.

4. Giving up if picked by a second blocker.

5. Not being prepared for quick count.

6. Giving up when you think the play is over and not going until the whistle blows.

7. Wearing unnecessary pads, bandages, tape, etc., that hinder rather than help a performance.

8. Anticipating the snap count.

9. Appearing tired, out of shape or dragging your body on or off the field.
