Sorry thats a typo.
In terms of zones a buzz zone(red/purple) is good against deeper routes towards the sidelines like a deep out or a corner route. Flat zones(light blue) cover outside of the field close to the line of scrimmage. Hook zones(yellow) are used by linebackers and sometimes safeties to cover the middle of the field. Deep zones(dark blue) are used by safeties to cover the deep parts of the field.
For a player to be considered athletic I like speed and acceleration to be around 90 but I prefer closer to 92, also for corner backs I also factor their man coverage rating into their athletic ability, the same goes for the so called "smart players" I look at awareness and zone coverage ratings.
Break tackle is a general rating and the elusiveness(making defenders miss) and trucking(running over defenders) ratings make things more specific. If a player has a high break tackle than they generally either have a high elusiveness or a high trucking or sometimes both. Hope that makes sense.
Pancakes are when an offensive linemen knocks a defender down.
QB Contain is used to keep the QB in the pocket formed by the blocking offensive lineman, the defensive ends loop out to prevent the QB from getting outside. A QB spy is used to have a player track the QB at all times. Generally a linebacker is spying but in some defense like the 4-2-5 the safeties can spy the QB. When a player is spying the QB that player will follow the quarterback where ever he goes. Very effective to prevent QB scrambles.
I did a quick look and couldn't find anything that explains the rating but if you look hard enough you could probably find something.
Once again I hope this helped and feel free to keep asking questions.
