Parker may have changes he wants to make to build his own defensive staff, and current assistants may yet explore new options or draw interest from other clubs also undergoing offseason turnover. Count Aaron Whitecotton among that latter group. The Cowboys defensive line coach has been requested for an interview with the Tennessee Titans for their current defensive coordinator position, per a report Friday from ESPN's Jeremy Fowler.
