This is a depth move
No, this is not the Titans’ solution to replace the recently-departed Jurrell Casey, who was traded to the Denver Broncos for a seventh-round pick a few weeks ago.
Let’s not forget that Tennessee also lost Austin Johnson to the New York Giants in free agency, who was valuable depth on the defensive line last season.
As long as he makes the roster out of training camp, Tennessee will fill that void with Crawford, who has spent most of his career as a backup.
