The release of the first depth chart, even an unofficial one, is always reason for intrigue.
After all, fans have been speculating for months where certain players fit into the roster hierarchy. True, plenty of spots (QB1, WR1, EDGE1, etc.) offer basically no reason for uncertainty, but there are plenty of spots that leave more room for doubt and conjecture. The Vikings shuffle along the iOL is one of the particularly notable components of the depth chart.
In particular, the new assignment for backup OT Blake Brandel is one that catches the eye.
