Defense Information C2 vs T2
I can't find the last one I posted on this topic this summer/spring so I thought I'd put another info post up so that people can understand the differences between the 2 and why I keep harping on the need for a Warpig.
I love this one......Gives you alot of history on how defenses evolved on how the DLmen, LB'rs and DB's work in the T2 and C2....
All 3-technique tackles are not alike. Defensive coaches continually search for ways to make their defensive linemen more effective. One of those ways, which was later adapted to the Tampa-2 defense by Tony Dungy and Monte Kiffin, was to slide the defensive tackles away from the strength of the offensive formation instead of playing them in even alignments over the offensive guards. This "undershifted" front makes it very difficult for the offensive line to double team the 3-technique, or in this case, undertackle.
The lineage of great undertackle includes many of the league's other most successful pass rushing defensive tackles. John Randle, the first undertackle in what would become the Tampa-2 defense, racked up nine consecutive seasons of ten or more sacks. La'Roi Glover's 17 sack season in 2000 came as an undertackle. Kevin Williams, Rod Coleman, Vonnie Holliday, Tommie Harris? All have had very successful seasons playing 3-technique on defenses frequently using underfronts during the last five years. The Giants nickel pass rush that used four defensive ends to wreak havoc on offensive lines early in 2007 frequently moved Osi Umenyiora or Justin Tuck into undertackle-like roles.
The implications of our discussion of undertackles should be crystal clear. While conventional wisdom suggests ignoring defensive tackles altogether for IDP roster purposes (and rightly so in most cases), you can now see why and when it's acceptable to deviate and target this special class of defensive tackles. As we hinted above, nearly every team that uses the Tampa-2 frequently (now just IND, CHI, BUF, MIN and in smaller doses than in prior seasons) should be scouted for an undertackle worth rostering. Be on the lookout for other 4-3 teams that aren't Tampa-2 teams, but use some undershifted fronts like the New York Giants, Seattle, St. Louis, Cincinnati, Houston and Carolina. Watch for mentions of undertackle and 3-technique in each team's defensive line discussions and be alert for those 4-3 depth charts that list one of the two DTs as a nose tackle. Very often, the other tackle is a 3-technique.
It's not at all uncommon to see a previously marginal talent explode for big numbers as an undertackle - as Cory Redding and Jovan Haye have in recent seasons. Vonnie Holliday's renaissance in his early 30s was directly attributable to his move to undertackle in Nick Saban's defense in Miami.
With the Tampa-2 defensive scheme no longer the hot defensive fad it was earlier in the decade, 3-technique tackles may be harder to find. But quick, powerful, penetrating tackles won't go the way of the dinosaur. Expect to see more teams scheme the underfront into their nickel packages. As Mike Nolan did in 2008 in San Francisco and the Arizona Cardinals did under Clancy Pendergast, the 3-technique tackle in an underfront may become a common sight among the newer 4-3/3-4 hybrid front defenses beginning to take over the league. Watch for players like Glenn Dorsey or Robert Ayers to work into 3-technique roles in their team's new hybrid schemes. Brandon Mebane (SEA) or Adam Carriker (STL) may also see more time in 3-technique roles under new defensive coaches in 2009.
Okay, so it might be a stretch to call Jimmy Johnson the lone driving force of the move back to the 4-3 front in the 1990s, in college or the professional ranks. But the attacking style of defense he brought to the NFL from his days as a college coach continues to impact the league today.
Johnson knew he couldn't recruit successfully against the big schools in his first head coaching gig at Oklahoma State. So he recruited athletes - football talent and size was nice, but speed and athleticism were what he wanted. He simplified the 4-3 scheme to a bare bones approach. No reading and reacting, no controlling your gap assignment. Instead, he coached his players to attack, penetrate and swarm along the front seven and used simple zone coverage in the secondary. He took safeties and made them linebackers. He turned linebackers into speedy, edge rushing defensive ends. Within ten years, a huge number of college coaches followed suit and turned out the players (and coaches) that would change the face of defensive football in the NFL.

- Cover-2 teams must have very talented safeties and a solid pass rush. Each safety has to be able to cover an entire half of the field. They need range, closing speed, tackling skill and enough run-pass recognition ability to not get fooled by play-action. It's extremely difficult for one man to handle the deep middle and the deep sideline. Having an average safety behind a poor pass rush that gives the quarterback time to wait for the deep routes to develop is a recipe for disaster.
- The Cover-2 can also be beaten by flooding one side of the zone with multiple receivers running routes on multiple levels. Force the safety, corner or outside linebacker to make decisions on which receiver to cover and another route may be left open. That was made painfully clear to the Washington Redskins last year when the Cowboys used Terrell Owens, Patrick Crayton and Jason Witten to pressure one side of the Redskin Cover-2 with a combination of sideline, seam, out and deep middle routes.
- Cover-2 teams, by definition, put only seven players in the box and are susceptible to the run. They hope to successfully take away the run without dropping a safety into the box. A team that wants to run Cover-2 because their corners struggle in man coverage but can't stop the run with the front seven is in major trouble.
- Cover-2 teams, by definition, can't blitz a linebacker frequently. The linebackers and corners can take more underneath zone responsibility, but the pressure must come from the front four. As mentioned above, a Cover-2 that can't generate pressure goes from a bend-but-don't-break style of play to one that gives up big plays in bunches when the deep routes come open downfield.
Couple on how the MLB is used for both variants.

2. Cover 2
– Basically means you split the field in half using the center as the middle. Each safety has deep halves (deep as the deepest receiver on their half of the field). The corners have the flat, the OLB's have hook to curl, and the MLB has what I call the short hole (the void left when the OLB's bail out to the curl). All NFL
teams play some form of cover 2 some of the time. As for the dreaded Tampa 2, the only difference between it and the Cover 2 zone is how deep the MLB has to play. In a Tampa 2 the MLB drops 10-15 yards into coverage to take away the cover 2's biggest weakness, the deep middle.
Alot of you keep harping on our MLB and how far he drops. Keep in mind that we don't run the T2 but rather the C2.
These basic coverage schemes, and variants on them, are as old as the hills. Typically, a Cover 2 splits the deep part of the field into two halves, and the two safeties provide deep help for the outside corners. Underneath, the corners and linebackers split the fields into five short zones. The defensive line is responsible for generating pass rush.

The Cover 2, with or without the "Tampa" modification, relies entirely on the front four to generate a pass rush. With the linebackers fully committed to coverage, the front four must get at the quarterback or risk the zone coverage being picked apart.

Cover 2, Tampa-2
The one secondary scheme that basically changes all the rules is the cover 2 and it's variation the Tampa-2. The Colts and Bucks have used this scheme for years and now several others have joined them including the Bears, Vikings, Lions, Bills. In all there are 6 clubs using this scheme on a regular basis and a few others who have it in their playbook for situational use. The basic difference between the normal 4-3 and the cover 2 is that in a cover 2 both safeties take on free safety responsibilities with each covering half of the field while the corners are asked to play more aggressively underneath. They usually move up closer to the line of scrimmage where they can be more physical with the receivers, often jamming them at the line and trying to alter their patterns. Being positioned closer to the line, the cover 2 corner generally has a much bigger role in run support. In fact the strong side corner often takes on very similar responsibilities to the strong safety.
