Exactly why they didn't. People think the coaches are that stupid, to call that play as much as they do on 3rd and long, without good reason? I don't care how bad we think garrett and Linehan suck... They aren't that completely stupid. They just know the chance of Dak making that is much lower then the screen.
No one in that organization is concerned about losing their job. Dak already comfortable he is the 10 year plan. Garret is on the Landry plan - Hell people annointed him that in 2007
Nothing is will change as long as this coaching staff is here. We do ok on the scipted plays early but after thst we settle into the same predictable offense week after week
