IMO Barclay is a backup OG masquerading out of unfortunate necessity as a backup OT. The Packers are dangerously thin at OT and not because of injuries: There are two players designated as “T” on their roster, one designated T/G (Barclay). None on IR. And one, Jeremy Vujnovich, on the PS.
IMO Tretter, Walker, Barclay and Taylor provide pretty good backups inside but OT has to be replenished next season. Competition to Bakhtiari would be fantastic, but at the very least one addition who has a realistic chance of being an average backup OT is needed – and that aint Barclay.
