As the Dallas Cowboys prepare for their final preseason game against the Chargers, significant roster decisions loom ahead of the regular season. Tyler Guyton has emerged as a strong candidate for the left tackle position, while the defense has shown promise with five interceptions in two preseason games despite the departure of Dan Quinn. The running back competition remains fierce, with Royce Freeman, Deuce Vaughn, and Malik Davis vying for the last roster spot, although Freeman's injury may hinder his chances. The Cowboys' depth chart is taking shape, with some new defensive acquisitions like Jordan Phillips and Carl Lawson, while CeeDee Lamb remains on the Reserve/Did Not Report list. Players like Kemon Hall and Andrew Booth Jr. are also looking to solidify their spots in a crowded cornerback position, with Hall's veteran experience being tested against younger contenders. The final preseason game will be crucial for many players as the team approaches the cutdown to a 53-man roster.
