Title: Mechanics
Post by: lonnieritch1981 on May 29, 2023, 03:21:53 PM
Settle a dispute about 7-man mechanics.  In a trips formation on the FJ side of the field, the FJ has the #1 receiver (the one closest to the sideline), the BJ has the #2 receiver and the LJ has the #3 receiver.  If the #3 receiver swings out to the sidelines and runs a go route down the sideline and the #1 receiver runs a slant toward the center of the field, how do the keys change for the covering officials?

You may frequently hear the expression "man-zone-ball." Well, that is a very over-used and far too general expression. You have to be able to see your primary key, plus other receivers. As long as your receiver is closely covered, you need to stay with him, regardless of where he goes, until the ball is in the air, and even then, obviously, if the ball is going to him. If your key isn't tightly covered, you should be able to check other receivers, perhaps even come off of your guy to pick up the guy that is the "threat" to be fouled. So, in the case of this crossing action, you have to identify the 'threatened' receiver, and, if he has moved from outside your general area, into your general area of the field, you need to recognize that, and focus your attention on the receiver that is the "threat." If your primary remains closely covered, then you MUST stay with him. But, if your guy is not closely covered, then come off of him and look for the "threat." Once the ball is in the air, then all eyes of the deep guys, in particular, must go to the intended receiver.

Would love to see a video.

Are there any receivers that end up "shallow" in the route?  If so, the LOS would probably break off and take that one.
But, if you have all 3 receivers running deep routes, the LOS probably stays with #3.
Again, I'd kind of have to see it, because sometimes you have to "feel" the route to best pick who is going to cover it.

I agree with this - without knowing what #2 did, it's hard to say.

Just for clarification purposes in trips formation, the LJ's (or HL if the formation is reversed) initial key is the #2 receiver unless the #3 is a tight end or a tight wingback who is lined up outside of the tackle box at the snap. See pg's 75, 169 and 171 of the 2022 mechanics manual. (I realize the mechanigram on 75 is for 8 man but he LOS and deeps are the same in 7 and 8)
