Look, what he is telling you is, who would start where, if the season started tomorrow. As the line is currently comprised now.
In fact, I can virtually guarantee it won't be. Before all is said and done, there are still at least three big dates on the free agency calendar, and the draft that will provide more offensive linemen. It is far more likely than not, that at LEAST one new starter will be introduced to the team before training camp starts.
There's a high degree of likelihood that number will be two new starters before training camp.
What Schnieder said is NOT, NOT, NOT the same thing as telling you that, "This is the starting lineup for 2016."
He never said, "OK we're done in free agency, and will not be looking to draft any o-linemen."
