Callahan may have been the guy to sign off on Nate Livings and Mackenzy Bernadeay (too lazy to look up if they all came here the same year). Maybe Jerry is willing to let him go since he burned them on those two. I know that sounds Zone'ish but I have a feeling Frank Pollack is more than ready to be the OL coach.
Also, I ran out of things to watch and listen to on my trip back from Louisville. I listened to the last episode of the Draft Show and they said Stephen told the season ticket holders that had they not traded up for Demarcus Lawrence, the picks would have been Kony Ealy and Trai Turner. We had already known that they tried to trade back into the 3rd to get Turner. That tells me we aren't done upgrading the O Line. Whether it was due to Free's pending free agency or Leary's shaky knees, they clearly wanted to add Turner even after drafting Zack Martin.
