A key injury up front and a willingness to change things at left tackle made TCU's offensive line look different against Iowa State.
Left guard Cordell Iwuagwu missed the second half of last week's loss to Texas (undisclosed injury) and did not play against the Cyclones. He had previously started every game at LG for the Frogs dating back to the beginning of the 2017 season. Chris Gaynor replaced him, allowing Wes Harris to start at right guard.
