In this week's blog, we will cover some defensive
terminology for relative newcomers to the NCAA Football franchise. With NCAA Football 11 seeing the return of
Formation Subs, understanding the coverage schemes will help all players learn
what type of players to recruit and place into each specific formation. In addition, learning the strengths and
weaknesses of each coverage shell will help improve your play-calling on each
side of the ball.
Today we will look at 'coverage shells' which refer to the
responsibility and assignments for defensive backs. Most exist in all base formations. For example, you won't see any Cover 4 in 4-4
as there are only three defensive backs in that formation. (You can audible/hot route to a Cover 4, but
the fourth defensive back will be a linebacker and perhaps highly exploitable.)
Cover 0
This is a man-to-man alignment with each defensive back lined
up against one receiver. It is helpful
when calling for blitzes as players can drop off of their assignment to go
after the quarterback. With a Cover 0,
there is no safety back on the play so if a receiver beats his defender, there
will be no help deep to break up the play or make a touchdown-saving tackle.

Cover 1
In this alignment, all defensive backs are lined up in
man-to-man coverage on a receiver except for one. Typically a safety, this player will be in
zone coverage, guarding the middle of the field. The biggest challenge with a Cover 1 is that
the safety must cover a wide area of the field.
Offenses may counter a Cover 1 by having the two outside receivers go
deep. If they can get past their
defenders who are in man coverage, the safety must decide which receiver to
help cover. This will leave one-on-one
coverage on the other side of the field.
Cover 2
In a Cover 2 scheme, the free safety and strong safety play in
deep pass coverage, each covering one half of the field. A 'Cover 2 Man' defense means the other
defensive backs and linebackers will be matched up one on one defensively. 'Cover 2 Zone' has the other defensive backs
and linebackers dropping back into zone coverage.
One variation and a very common defensive scheme is the
'Tampa 2.' In this scheme, another
player (usually a linebacker) will drop into a zone in the middle of the field.
In a Cover 2, the cornerbacks are able to defend against the
run, short passes, and deep passes knowing that they have help over the top
from the two safeties. Offenses will attack
a Cover 2 between the safeties. If the
safeties move towards the sidelines to help cover fast wideouts, a tight end on
a post route forces one of the safeties into making a quick decision. Should he cover the middle of the field or
help cover the wide receiver on the outside?


Cover 3
The Cover 3 has three players in zone coverage deep, the
free safety and two cornerbacks. The
strong safety can then play more like a linebacker by moving closer to the line
of scrimmage and go into pass coverage or blitz the quarterback.
A Cover 3 is susceptible to short outside passes as the
cornerbacks are dropping into zone coverage.


Cover 4
A Cover 4 utilizes four defensive backs in pass coverage,
each guarding one-fourth of the deep zone.
This coverage is very effective versus deep passes and is utilized as a
prevent defense at the end of a half or game.
When utilizing the Cover 4, your defense is very susceptible
to the run and short pass, but has the goal of minimizing big plays and hoping
the clock runs out before surrendering a score.
Conclusion
Hopefully learning about coverage
shell terminology will help you to learn more about what type of defensive
backs to recruit in order to fit your preferred system (and use in Formation Subs
in NCAA Football 11), the advantages of each defense, and also its weakness -
so you know how to attack this defense when playing your next foe.

Football? If so, please leave a note in
