Would be interesting if they tell us how the come to all those "rates"... maybe I missed it. Landry when playing like last year is a pro bowl caliber safety, easily. Yes, he was beat for a touchdown here and there but I remember for example one being by Brady to Gronk with was an indefensible play that Landry covered as well as you can cover it. Then he is also a leader, someone who gets his teammates fired up, puts fear into receiver's heads going over the middle and just is a very energetic player. That will not show up in any stats or rates.
The one reason why you gotta be careful with him of course is the injury.
