Uh, not rambling at all, that was excellent and you far exceeded my hopes for an answer. Thank you, I legitimately feel like I understand this better now.
For most fans it’s easier to understand the “packages” used by the offense because that’s is what TV or radio commentators talk about.
1 RB, 1 TE and 3 WR is probably the most common grouping used by offenses today. But this grouping can be used in multiple formations.
- TE left, 3 WR right, RB straight up, offset left or offset right.
- Flex the TE (move him away from the tackle) creates a four-wide look. RB straight up, strong (near the TE; becomes second possible receiver to that side). RB weak (away from the TE) become possible 4th receiver to that side. The same personnel grouping in different formation presents different threats to a defense.
Motion and shifting players from one formation to another is used to allow the QB to see what a defense is running; man vs zone or blitz or the most common defensive calls exposed. Sometimes this is done to see what a defense is doing on the current play. It is also used to show coaches what the other team is doing for reference on future play calls; 3 and 7 from the field position, when we were in formation A and motioned to formation B the defense did this, so call a play that takes advantage of the defense when they do that.
Coach Nixon uses a lot of motion and shifting to see what a defense is doing and in an attempt to creat a mismatch.
Teams have tendencies out of certain personnel groupings, certain formations, in certain down and distances situations in certain part of the field at certain parts of the game. Defenses scheme or game plan to address all of theses tendencies.
Some of the best parts of a game occur pre-snap. Pay attention to the offense’s personnel groupings, then see if the defense changes any of their personnel. The pre-snap does the offense shift formations or uses motion. How does the defense adjust to the motion or shifts? Then… let’s play Coaches upstairs are charting everything l.
Teams out together a game plan based on information they have from film, scouting reports from other coaches they know, injury reports and anything they can gather. The game plan is the base for the day but usually only good for the first series. After the first series both teams will adjust their respective game plans based on what they see the opponent doing today. See the UNC/TCU game last night. On the first drive UNC made it look easy and scored. Then TCU made some adjustments and the game changed. There are always certain phases to a game; 1) the game plan, 2) the adjustments to what the opponent is doing today, and 3) the adjustments to their adjustments. At a minimum, this occurs each half.
I love this game.
Go Orange!
