I'm don't know what his pass rush or run stop grade is but he looks like a prototypical NT to me like Vince Wilfork, Ted Washington or Dontari Poe.
Not sure what eye-popping stats you expect from a two-gapper but guys like I mentioned above made multiple pro bowls just by pushing the pocket and tying up blockers.
Davis is going to have tremendously more value to a 3-4 team looking for that Big anchor in the middle.
He also looks to have the highly coveted 35" arm length for a lineman.
He might even be able to play some 5tech like Albert Haynesworth used to.
