Not a Williams thread, but since you are talking about him, his huddle doesn't show he seeks contact. Hard to see him pull a Rousseau if he's not ready to get bloodied. Even as an OLB or Rover/striker, I worry about his tackling instincts. I know he's got elite athleticism. I just don't see an easy path to exploiting it against top P5 opponents.
Kinchens, on the other hand, is going to slide right into a starting safety spot by end of year two. That HUDL shows him shutting everything down at single-high safety, disruptive off the line in a safety blitz, even running a punt back for a touchdown. He's a baller, the perfect Safety for a Diaz defense.
