That's an interesting one. At 238 he'd be pretty damn big, but that's how big Roy Williams was, Taylor Mays is that big, as is Adrian Wilson -- and Joey Browner in his heavier days was probably in the 230s.
Still, that's a pretty big dude for SS. Does he have the speed and range to be anything other than the rolled down S in a cover 3? I wonder what kind of ground he could cover in a two deep scheme, or if he could handle a TE or a HB.
