Carolina eschews the OL for another DT.
Kawann Short is a fairly athletic DT from Purdue: 6'3, 300. He has a good reach (34.7" arms) and ran a solid 5.09 40.
Short was a two year Captain at Purdue, and a 2nd team All American.
He's billed as being a potentially incredible DT, who has an inconsistent motor. Obviously, the Panthers have age concerns on Dwan Edwards, who's 33.
Carolina likely won't be run on. They have longterm defensive tackles, assumedly, for the first time in forever. There's contingency in place for Edwards' phasing out.
There were other DTs I liked more personally (Jesse Williams, who was mostly a NT, but who is athletic), and I preferred an OL by far over another DT at this point.
