The primary issue is his size. He’s just not very big by most O-line standards. They signed him to be a mobile center in the zone rushing scheme that the Kubiaks loved to deploy. Straight up pocket protection he is more or less just a body.
That’s why you don’t draft 280lb Centers, let alone drafting them in the first round. Spielman should have been fired on the spot.
And don’t anybody come back with telling me he’s 300lb..they may list him at that but there’s no frickin way he’s 3 bills..
