Big-bodied, battle-tested Houston OL with real pass-protection chops
In the 2015 season, Houston’s Zach Johnson looked like a sturdy right-tackle option at 6-7, 315, starting three games before an injury ended his year; he allowed just one sack in 332 offensive snaps and graded out at 80 percent on Houston’s line sheet. That profile says “dependable road-grader” more than flashy athlete: long frame, experience, and enough anchor to handle pass protection while helping open run lanes. The caution flag is health, since his season ended after he missed the back half of 2015, so he fits best for a team that values size, experience, and grit over upside fireworks.
