The Dallas Cowboys hit the field for the first practice of training camp on Tuesday, July 22, and we will get our first look at players in pads going full speed. In less than 20 days, the Cowboys will see their first live game action with their first game of the NFL preseason. As has been the case, Dak Prescott will not see the field during preseason, which means we could see an extended look at backup quarterbacks Joe Milton III and Will Grier — make that Super Bowl champion Will Grier. Last year, the plan was to get Trey Lance a lot of reps to showcase his skills and he underdelivered.
