As expected, the Dallas Cowboys have been slow starters in free agency this year. The team building strategy has always been to build the roster through the draft and only use free agency to fill holes with bargain players. 2021 appears to be more of the same. In this Dallas Cowboys 7-Round mock draft we do an extensive defensive rebuild. The Dallas Cowboys are being free agent opportunists right now, grabbing and filling wherever the value presents itself. This will keep Dallas from reaching for need in the draft and at the same time won’t prevent them from any positions either.
