I would say that Jamarco Jones is the highest grade OT. Rankin is versatile. He was THE top JUCO OT when he transfered to Mississippi State. He lost playing time his senior season due a high ankle sprain and STILL made first-team All-SEC. He seems best suited to play center.

EDIT to add NFL.Com
OT, OLB, and S grades

OT Jamarco Jones 5.86
S Kyzir White 5.81
OT Martinas Rankin 5.76
OLB Darius Leonard 5.74
OLB Jerome Baker 5.71
OT Brian O'neill 5.71

If you think about it, in this mock, the Jaguars draft taking OT Orlando Brown was wise in subtraction by addition.
