Garrett had nothing to do with the running game. That was built by Callahan, who we lucked into, the guy Garrett feuded with. Garrett brought Houck with him and used man-blocking schemes and our RG was absolute garbage. Look at the trash Garrett lackeys trotted our before Bill came. And the only reason we went Smith during the Garrett era is because Flozell left and Jerry knew the importance of the LT position when Flozell went down in 2005 and the OL proceeded to give up over 40 sacks in ten games.
Callahan came and completely rehauled the OL with zone blocking schemes. He brought in Leary and was instrumental in the Frederick pick, while Garrett and Stephen Jones still though that Sharif Floyd was the top pick Dallas was going to take. Further, before Martin was picked we had three defensive players on the board that were all taken. Garrett had no clue and this idea the OL was part of his vision is hogwash and laughable. Collins chose us as an un-drafted FA after he fell in the draft and it was because of Jerry recruiting him.
Further, the run game usage was actually a product of Romo given reigns of the offense in 2014 and Zeke was drafted for him. And the RG from Callahan was so effective it made Jerry start to take play calling duties away from Garrett. After 1 year, Jerry promoted Callahan to play caller. And further, the Cowboys drafted Zeke for Romo period..
