The Bears had lined up in I-formation for their first offensive play of the second half Sunday when they saw Texans linebacker Blake Cashman creep toward the line of scrimmage. That triggered the Bears’ offensive linemen to change their blocking assignments — a blitz was coming to the strong side.
Center Sam Mustipher snapped the ball and took three steps forward, toward his right. Texans defensive lineman Roy Lopez went the other way — around Mustipher, to his left. Mustipher put his right foot in the Soldier Field turf and pirouetted Lopez’s way, turning his shoulders as if he was letting someone pass him in a crowded hallway.
