Well he did it three times, as did another CB and it really dug us a huge hole as you can see below. Both Vision and Agility are very high on both players. I'm curious if this is a run focused issue.
Knowing the build would help a lot, but it does look like he may be on run focus with the way he jumps forward. The first 4-6 ticks were spent with him inching towards the line, not into pass coverage.
It could also be some bad vision, though, because I looked at a few other plays with him in it and he seemed to react (going into pass coverage) pretty slowly.
