I would find it odd because Barclay is the one who has to be replaced first and that means Bach or Sherrod have to move right as well. Bach spent next to no time on the right last year and Sherrod hasn't since his injury.
And RE: the blurb Patler had, I don't know how you can actually be the left tackle in a one on one drill. Maybe as mission said, it was about the angle and footwork.
