What do you guys think of this write up?   First off a screen play is an outside behind the scrimmage pass play.  It's designed to take advantage of aggressive defenses.  It does this by allowing D-Linemen to penatrate and then throwing outside their penatration.   The receiver can either be a running back (the traditional screen) or a wide receiver (the bubble screen).

Now here some links to some good articles covering the screen pass.   Also I would love to get some input from some of the other Xs and Os guys

Pat Kirwin does a great job explaining the use of the double inside blitz, in the Philly game.  He goes on to explain what could be done to counter it and what was done.  Plenty of good diagrams to help explain things.

Jimmy,

My opinion is that either defense can be very effective.  It's all a matter of having the right players and a good DC.   I think the 4-3 can be extremely effective when you get someone in the DT position that can get a consistent push in the middle.  This year's Giants and the Warren Sapp Tampa defenses were two good examples of that.

I will offer my take Jimmy.   The 3-4 defense is one in which the primary pass rush pressure comes from one of the OLBs.   Usually one of the 2 OLB will be rushing on every pass play.   The NT is a pass rusher (on passing downs) as are the two defensive ends.  However because the NT is usually a very stout player, who needs be able to occupy 2 blockers on running plays, they usually don't get a great push up the middle.   For a 3-4 to get a good middle push they usually need to blitz a safety or an ILB.   Ottoman offers some good insights, but I don't think you usually see the ends lining up over the guards (at the pro level).  I have usually seen them lining up over the tackles or between the tackles and the guards.  I have a couple of good links to articles as well as a flash video and a picture of the basic alignment

That's a good question Jimmy.  I will let some of the others get the first shot at answering this.  If no one steps up, I will give my best answer.

Thanks for the input and welcome BLD.

Excellent work Painter.   Here is an article that covers zone blitzes.  It includes some diagrams and it covers the zone coverage concepts.  Painter's work is at a pretty high level, so this article might be useful to fully understand it.

The box under Bill and Hillary

In general the safety position requires the following dimensions, to handle the different role.   They need to be 6 foot or taller (although 5-11 isn't uncommon).  They need to be 200+ pounds.   They need to be good tacklers (hard hitters prefered).   Finally they need to be skilled in zone coverage, as that is the primary coverage most safeties will use, the majority of the time.

When you look at Madison: 5-11 180 lbs   Not big enough.  Plus his strength is M2M rather than zone and he is an average tackler

When you look at McQuarters: 5-10 194 lbs  again he is under sized.  He is an average tackler and his coverage skills are unremarkable.

This is a good topic.  Once it falls off the front page, I am going to move it over to the Chalk Talk board.  This is a perfect topic for that new board.

Painter is correct the names are defined by the roles in the defense more than a player's attibutes.   While I don't have hard numbers to back this up, it seems to me we have seen safeties get a little smaller and faster over the past decade or so.   So in  way they are adopting to the trend you have noted BCBud.   
Still in most defensive schemes the tackling ability of a safety is challenged far more than that of a cornerback.     In most between the tackle runs, the safeties are the last line of defense.  A missed tackle by either on of them, can result in a long gain and touchdown.   
They are also the player that is brought down closer to the line of scrimmage to take on duties, similar to a linebacker, when you put 8 men in the box.   So again the safety needs to be stronger tackler.   
On the passing side of things, I think you see corners used in M2M far more often than you will see a safety being called on to do so.  When safeties are called on to cover M2M, it's usually a running back or TE.   These are players where a little more size and strength are helpful.  So there is another reason why safeties need to be a little bigger and stronger than a corner.
It's my opinion that the need for quality safeties has grown over the years.   They are needed to handle the increasing numbers of big athletic TEs, to handle the good running teams and provide much needed help in covering the pass happy offenses.   

It's all about the game.  Anything to do with Xs and Os or other similar topics is welcome here.  If you have a question, post it and others will answer.  If you want to help educate others, post a thread.   If you want to talk about a topic, just post it up.

WOW!  Imagine if a Giants QB (or any player for that matter) called out his teammates as "lazy".

Finally here is a simple passing tree for a WR on the left side and a RB passing tree.

Now I will give you a slightly different take:

Pass Route Tree
.
The Pass Route Tree (below) illustrates the basic pass routes run by eligible receivers.  As a rule odd numbered pass routes are run to the inside portion of the field, even numbered routes to the outside.  Basic patterns are to the left in the diagram, specialty routes to the right.  Pass routes can be called by number or by name.  In a passing play like the 838 Deep Cross, the numbers specify that the outside receiver run a #8 patter, the man next inside him a #3 pattern, the next receiver another #8 pattern.  Of course, patterns can be modified.  For example the Float is merely a soft, dragging slant pattern.  The out and up is a combination of a five yard out pattern and the Fly pattern. The pass routes or patterns depicted here are numbered as follows.  #0=The Zero or Curl Pass.  #1=5 yard Cross or In.  #2=5 yard Out or Sideline.  #3=10 yard Cross.  #4=10 yard Out.  #5=10 yard Hook or Stop (In).  #6=10 yard Hook (Outside).  #7=Post. #8=Post Corner.  #9=Fly or Go.  I personally do not favor pass route numbers higher than one digit as this hampers many play calling techniques.  Other pass routes can be specified by letters of the alphabet or by name, as in the Flag, Fade, Slant, Float, and the Out and Up.  Many coaches use what I call the Banana route where a pattern such as the Post is rounded or bowed in shape.

Other Pass Plays
.
    The Out and Up Pass is a dangerous play designed to take advantage of single (Man to Man) coverage.  It requires some "setting up" by having a receiver run the #2 pattern--the five yard out pattern--several times previously.  Then the quarterback simply calls the out and up, the receiver runs the out, the quarterback "pumps" the fake pass, then hits the receiver on the fly.
    The Curl Pass simply calls for a receiver coming out of the back field in the Curl or Zero Pattern.
    The Hitch Pass calls for multiple receivers to one side of the field, then the primary receiver simply steps back a step and catches the quick toss following the blocking of the other receivers around him. One or more linemen can pull around the corner to offer blocking assistance.
    The Hitch and Go calls for a pump fake by the quarterback during the hitch, then hitting the receiver on a fly pattern.  The Hitch and Go is set up by first running a few hitch plays.
    The Hail Mary involves multiple receivers coming together at one deep spot in an effort to outnumber the defenders at the point of reception.
