Schlauderaff was a sixth round pick from Utah. According to SB Nation's Packers blog, Acme Packing Company, preseason was not great for him.
But it was a brutal night for second year tackle Marshall Newhouse and rookie sixth round pick Caleb Schlauderaff. At right tackle, Newhouse was often overwhelmed by nearly every move made by the defensive end, and he let his man go straight for the quarterback on a few occasions. It wasn't much better for Schlauderaff, who struggled badly in pass protection at right guard before moving over to play some left guard in the 4th quarter.
Positives: Gets in the way and can seal lanes. Functional positional blocker. Flashes some pop in his hands. Fairly dependable, experienced, four-year starter. Coachable, team player. Works hard and plays hard.
Negatives: Average arm length. Plays too small. Does not create a push in the run game. Struggles to reach the block point and adjust on the second level. Soft anchor in pass protection - gives up ground and struggles to adjust to movement. Inconsistent hand use. Faced marginal competition in the Mountain West Conference.
He is 6'4" and 305 pounds. It sounds like he is a purely developmental guy. We will see what Bill Callahan can get out of him, but it might be ambitious to expect too much soon.
Incidentally, Notre Dame is in a lightning delay so they are showing the Irish's game against Utah from last year right now on NBC.
