Regarding trail technique. Getting into a trail position is if option A fails. What Saleh really wants is for the CB to be hip to hip with the WR with optimal positioning being the CB's outside shoulder (shoulder closer to sideline) on top of the WR's inside shoulder. At that point look up for the ball because the CB is now controlling the WR, able to body up against him.
If the CB is unable to be hip to hip with the WR, that means he's now trailing the WR. Only then will the CB not look back for the ball, and instead play the eyes/hands of the WR. This is for vertical routes up the sideline.

This article explains the techniques a CB will use, with words from players we know (Eric Davis, Tim McDonald).
http://www.nj.com/jets/index.ssf/2014/09/the_art_of_defending_the_deep_ball_how_one_of_footballs_most_stressful_situations_is_getting_even_to.html
When a receiver beat him deep in a one-on-one practice drill, Landry decided to turn around and play the ball. That might feel like a natural reaction, but it is all wrong, because you lose track of the receiver, drift away from him and slow your pursuit, all at once. Landry said defensive backs are always taught to never look back for the ball until they are "in phase" with a receiver – basically running next to him, hip-to-hip.
What if a defensive back gets beat, and trails his receiver? In this situation – "out of phase" – the defensive back must look at the receiver's hands. When he sticks them out to catch the ball, the defensive back has to jab his own hand ahead to disrupt the play.
---------------
Here's Sherman in phase, outside shoulder on top of the WR's inside shoulder. He is in proper position to look back and play the ball.


Revis in phase. In both these plays, the CB goes for the jam by turning then punching with the arm that will eventually be the outside arm (outside = closer to sideline).

-----------
This is DJ 'out of phase'. His right arm (white sleeved) should not reach out like that. That's the wrong arm to use. Compare DJ here to what Sherman and Revis do above. Sherman/Revis don't use that upfield arm to jam at the line.


There is a problem with this 'play the hands' technique that gets CBs into trouble - when the pass is underthrown. When it's underthrown, we always think, "he should have turned around, probably could have gotten an INT". But if CBs are taught to turn around when trailing, they will risk (from the article), "lose track of the receiver, drift away from him and slow your pursuit, all at once."


imo the issue with DJ isn't so much that he can't play with proper technique when he finds himself out of phase, although it is an issue. But the main issue is that he is rarely in phase.
His feet lack movement at the line compared to the others. Get his feet into position quicker and he doesn't have to compensate using his right arm.

The others shift their weight very quickly, not sure DJ did that on his.

Completely agree. IMO, DJ's lateral movement is subpar and that affects him at the line in press. He might have the body type to play press, but he does not have the high end athleticism required to be good at it.

Have him gain 15 pounds and try him at SS. Otherwise, cut him, he's a liability at CB.

Here's the KW interception. The telecast was correct when they said there was no underneath route to hold KW, allowing him to gain depth.
Dagger vs Tampa2. Dagger (red + yellow + orange) is a vertical stretch targeting the Hook defender, in this case KWilliams.


The orange WR doesn't immediately release into his route. Instead, he first chip blocks Elvis.


Bortles is about to release the pass. The orange WR is lagging in his route because he chip blocked Elvis. Had he not chip blocked, he would probably be near the orange star, flashing in front of KWilliams, creating a vertical stretch.


KWilliams is not threatened by the orange WR and is able to gain depth. Enough depth to make one helluva INT.


Purrtty INT

Jam with correct arm, in phase, look up.


Nice celly. He should spoon the ball.

Wash your mouth out! These guys do a great job and put loads of work in, so what if they put an emphasis on someone who is fun to watch.

If you want to spend hours cutting up film you can post about whoever you want

JD, TH - amazing breakdowns. Can't even describe how useful this weekly thread is.

Humble request, do either of you have a gif of the PI call on Johnson? We need to send that to Saleh so he can finally see that DJ is not the answer lol.

Thanks guys!! Appreciate the break downs for D also. .

he should be our future #1 corner. no question
Well 49er fans, the bittersweet season that was 2017 is now over for us. It was a rough ride the first 9 weeks and was hard to keep watching losing football, even when you know it's a rebuild year. It seems like forever ago we fans were talking about Rosen and Darnold and whether or not we'd have 2 no wins teams in the NFL this year. What a difference a couple months can make.

While it would've been nice to see how we measured up against the cream of the NFC West next season it was still nice to get a W.

This was definitely the poorest performance by Jimmy G yet. That being said, even when it was a poor game, it wasn't a bad game. While it's not great to see a QB throw 2 picks in a game I've definitely seen uglier picks thrown. The 1st was just a great play by a defender in man-coverage. Jimmy didn't do anything different from other throws we've praised for throwing before Goodwin entered his break and trusted his receiver, one of those where you tip your hat to the defense. The 2nd wasn't the best, but again, wasn't terrible. I see why he threw it and his receiver did slip badly in his break. Probably not the best decision but, again, I've seen worse.

The defense played pretty well, though they were playing a quarterback who hasn't done anything and looked completely overwhelmed.

Standouts on defense were Foster(he had one really nice play where he matched Tavon Austin across the field), Reid, and Colbert. I would be interested to know why we flipped Johnson and Weathersppon in this game.

Overall it's been a fun season with a crazy last 6 weeks. Here's to looking forward to next season and a whole bunch more changes in the upcoming months!
