The preseason is finally almost here for the Cowboys and they’ll face the Denver Broncos in week 1 at Empower Field in Denver on Saturday. We won’t be seeing Dak Prescott or Ezekiel Elliott just yet, but this is our chance to see the rookies in real action – not just on the practice field.Who can we expect to see?This will be our first chance to see rookie OT Tyler Smith, EDGE Sam Williams, and rookie WR Jalen Tolbert take the field. Named as the unofficial starter alongside Lamb until Gallup returns, Tolbert is one of the rookies expected to have an immediate impact considering the Cowboys’ receiver situation right now (Cooper gone, Gallup and Washington injured).
