In part 5 of our series on the 3-4 defense and how it affects the Steelers’ draft, we will talk about the final component of the 3-4 defense; the secondary.

The secondary consists of 4 positions; the right and left cornerbacks, the strong safety and the free safety.  These positions are known collectively as defensive backs.

The role of the defensive backs in a 3-4 and a 4-3 are basically the same.  Their jobs are to defend against pass plays, and to tackle any runners who might get past the defensive linemen and linebackers.

Based on the situation, the team may bring in a fifth defensive back (the nickel back ).  In other situations, they may bring in a 6th defensive back (the dime back).  There are even situations when a team might bring seven or even eight defensive backs onto the field (like a game-ending ”hail Mary” pass play).  However, these situations are unusual.

Depending on the scheme, the roles of the defensive backs may vary.  For example, some teams play their cornerbacks in primarily man-to-man coverage.  Others may mix in some zone coverage.  Some defenses require their cornerbacks to line up close to the line and jam the receivers as they start their routes.  Others, like the Steelers, tend to play off the line and give receivers lots of cussion.

The Steelers require their defensive backs to play a more integral role in run support than most teams do.  In fact, a cornerback who is not strong in run support probably won’t fare well in Dick LeBeau’s system.

The cornerback is the player who is primarily responsible for guarding the wide receiver.  He has to be able to run stride-for-stride with the fastest receivers, and therefore, they are usually the fastest players on the defense.

The typical cornerback is about 5’10″ tall.  However, as more tall receivers like Randy Moss, Calvin Johnson, and Plaxico Burress emerge, as well as receivers with incredible leaping ability like Larry Fitzgerald, teams will need to find taller cornerbacks to defend them.  The Steelers’ Ike Taylor may be the new prototype, as he has the height, speed, and leaping ability to guard almost any wide receiver in the NFL.

The strong safety usually plays on the tight end’s side of the offensive formation (the “strong” side).  That is why he is called a “strong” safety.  The strong safety is usually the bigger and stronger of the two safeties.  He is also often the slower of the two.  He is often charged with guarding the tight end or any running  back who may leave the backfield.

A good strong safety will often be like a small linebacker on the field.  He will be excellent in run support, and is often known for delivering vicious hits.

The free safety is usually smaller and faster than the strong safety.  He typically lines up further back from the line of scrimmage than the strong safety.  He is usually the last line of defense in the defensive backfield.  He must have the speed and instincts to read long pass plays, and to quickly close the gap between himself and the receiver.  The free safety must also be able to play man-to-man on a wide receiver if the opponent utilizes a third wide receiver.

Interestingly, when you look at what is required of the free safety versus the strong safety, one might argue that former Steeler Anthony Smith was more of a strong safety than a free safety.  However, with Troy Polamalu entrenched at the strong safety position, the Steelers were forced to use Smith as a free safety.  He repeatedly failed to be the “last line of defense” against the New England Patriots, and that ultimately cost him his job.

Looking at this year’s draft class, there are a number of good cornerbacks in the draft, but few top notch safeties.  In fact, safety may be the weakest position in the draft.  There are no elite safeties in this draft, and there may be no safeties taken in the first round.

Cornerbacks:

Malcolm Jenkins (6’0″, 194 lbs.), Ohio State.  Jenkins it probably the top cornerback in the draft.  He has good size, plays a very physical game, and is good in both pass coverage and run support.  He has Pro Bowl potential.

Alphonso Smith (5′ 8 7/8″, 193 lbs.), Wake Forest.  Smith probably has the best coverage skills in the draft.  He has great hands, and rarely gets beat.  However, Smith’s small stature may prevent him from ever being a #1 corner. 

Vontae Davis (6’0″, 205 lbs.), Illinois.  Incredible physical specimen.  Has size, strength, and speed that few cornerbacks can match.  However, Davis’ mental attitude has been questioned.  He has had problems with coaches, and talks non-stop trash.

D.J. Moore (5’10″, 182 lbs.), Vanderbilt.  Moore has great ball skills, but he is slight of build.  Does not play physical, and needs to improve his tackling.  Will probably be more of a #2 corner.  Probably not a good fit for the Steelers’ system, where physicality and run support are mandatory.

Sean Smith (6’2″, 215 lbs.), Utah.  Rare size with long arms.  He lacks top end speed, but has the height to match up against bigger receivers.  He is a converted wide receiver who is still somewhat raw at the CB position.  Teams will fall in love with his size, but his skills need development.

Darius Butler (5’10″, 178 lbs.), Connecticut.  Outstanding athlete who was very impressive at the Senior Bowl and NFL Combine.  He has a thin frame, and struggles to break free from blocks.  He failed to get a single interception his senior year, and that will make some teams wary.  He has the ability to return kicks.  That will work in his favor.

Safeties:

As we mentioned earlier, there are no elite safeties in this draft.  However, here are some of the best that are available.

Louis Delmas (5’11″, 196 lbs.), Western Michigan.  Aggressive hitter with all the skills necessary to cover tight ends or running backs.  Plays much faster than his timed speed.  Played against questionable competition, but a good showing at the Senior Bowl may have made him the first safety to come off the board during the draft.

Rashad Johnson (5’11″, 195 lbs.), Alabama.  Played well in college, but lacks the ideal size for a safety.  Looks more like a cornerback.  Is a smart player who was a leader on his team. 

William Moore (6’0″, 223 lbs.), Missouri.  A big, physical playmaker who is great in run support.  Lacks top level speed, which will probably work against him.  He bites on fakes far too often.  He will need coaching at the next level.

The Steelers’ primary need is for a #2 cornerback to replace Bryant McFadden.  William Gay is already on the roster, but finding an upgrade to him won’t be difficult.    Vontae Davis would look good in black and gold, but his character issues will probably make the Steelers reject him if he is available.  Sean Smith has great physical tools, and would benefit greatly from Mike Tomlin’s DB teaching skills.

At the safety position, the Steelers need to find a replacement for Ryan Clark, who is getting older.   Louis Delmas is likely to be available at #32, but probably won’t last to #64.
