FRISCO -- Potentially losing Jason Witten and Dez Bryant in the same offseason doesn't sound like the recipe to making an offense more Dak Prescott-friendly.Bryant and Witten have been the two most productive pass-catchers during Prescott's two seasons as the Cowboys' starting quarterback.But leave it to Dallas owner Jerry Jones to explain late Friday night why all three draft picks -- Leighton Vander Esch, Connor Williams and Michael Gallup - have given Prescott a better chance to succeed."I think today and what we've done in free agency will give Dak more time," Jones said during a news conference after the third round of the draft.
