OFFENSIVE LINE

Shifts and changes abound on an O-line that must improve from last season’s struggles, particularly in run blocking. New position coach James Campen’s techniques should help. Laremy Tunsil, Houston’s best player, is back at left tackle. Tytus Howard moved from right tackle to left guard to bolster interior blocking with former Seahawks center Justin Britt and Max Scharping, who moved from left to right guard. Charlie Heck gets his shot at right tackle.

Then: Laremy Tunsil, Tytus Howard, Roderick Johnson, Nick Martin, Max Scharping, Zach Fulton, Charlie Heck, Senio Kelemente. Now: Laremy Tunsil, Tytus Howard, Justin Britt, Max Scharping, Charlie Heck, Geron Christian, Justin McCray, Marcus Cannon.
