The Jaguars used a sixth-round pick on Bowanko, who played all over the offensive line for the University of Virginia. It's assumed that Bowanko will work in training camp as a center and offensive guard, competing for one of the starting positions available at both spots.
With the new rookie slotting system under the current NFL CBA, signing rookies has come at a blistering pace, especially this season as some teams already have their entire draft class under contract.
I would expect the Jaguars rookies to beginning signing rather quickly and No. 3 overall pick Blake Bortles might take a little longer than usual, simply because of the position he plays, but all should be ready in time for training camp.
