I saw this. His grabbiness really concerns me at the NFL level. Surprised to see it so much out of a big school like Miami. He is the prototype for what Richard wants to run, though. It is rare that guys this big are that fast. Seems like a good pickup from where he was selected, but he definitely needs polish.
The Kris Richard scheme and CB Techniques with the scheme cause a fundamental change in the way CBs play.
It's almost like the difference in playing DE in a 3-4 vs 4-3. Both are called Defensive End but it's a much different position.
KR uses multiple different coverage(s); however, his base coverage has the CBs playing a man/zone hybrid that is based on how the WR reacts off the snap.
In this base coverage the CB does not worry about inside routes off the snap. Those are the responsibility of LBs/Safeties playing Zone.
The CB drops into an intermediate/deep sideline zone if the WR cuts inside off the snap but the CB takes the WR in man if he goes outside off the snap.
Either way the CB is covering the sideline area which narrows the field for the FS.
The key is the unique kick-step press technique. The CB basically stands in front of the WR and does not budge until the WR makes his cut.
If the WR cuts outside, then the CB presses him and uses the press to slow the WR while the WRs momentum actually helps the CB transition
to turn and run in stride with the WR.
The CB aligns with inside leverage which makes it difficult for the WR to cut inside.
Obviously they also play standard zone and off-man. If you see the CB covering inside routes it's in one of those coverage(s).
Summary:
The Kris Richard scheme alleviates much of the need for CBs to grab outside of the 5 yards area where contact is legal.
The CB in this scheme do tend to push the boundaries of physical play within the 5 yard area but the scheme and technique
eliminate much of the panic that causes many CBs to grab WRs to the point of getting a penalty.
The difference between Nickel CB Anthony Brown from 2017 to 2018 was dramatic.
The scheme in 2017 made it harder for him to succeed than average NFL schemes.
The scheme in 2018 made is easier for him to succeed than average NFL schemes.
