There was an article on DC.com about how Lucky is so dangerous with those screens. There was a comment during the OTAs that Terrance Williams is so good with those slants and Romo called him "one of the best players in the league after the catch". Beasley has been described as impossible to cover at short range passes and his runs after the catch almost always double his yards before the catch. Dez runs so violently and physically that you want the ball in his hands as fast you can. He takes those quick down and ins and take it to the house. Gavin Escobar has been described as being the tallest player on the field as well as some of the best hands on the team.
But Broaddus, Eatman, Romo, Archer, etc always end their praise of the players obvious strengths with "but they don't run those plays that often".
I just don't get why the offense is set up for Dez to wait to get the ball. Williams needs high percentage passes because of his anxiety but playing to his strength, he can take a short slant for a TD. Beasley, Whitehead and Escobar are all excellent in the short passing game and would virtually control the chains.
This group could and should be a strength but the question is; why is it so rigid that the plays are designed to "beat the player across from you" when most teams have faster players at CB than Dallas has at WR and TE. However, if the routes were designed more laterally and integrated freeing the WRs at the LOS the tremendous and elite ability of Dez, T-Willy, Beasley, and Whitehead to run elusively and manufacture yards, the team would be equipped for years and there would be no questions about the players (except maybe Devin Street who doesn't seem to fit into any category).
Frankly the slant and quick out are part of the Coryell 9 routes so they really don't need to change anything drastically. I think given who they have and what those players can do they should work more of those short passes into the games.
