Tracker Major Character Update Sets Up A Better Season 4

Trackerseason 4 is going to be a season of change for the hit CBS show, but a major character update is making things seem like they may wind up better than viewers have anticipated. Throughout the run of Tracker, which stars Justin Hartley as the titular tracker Colter Shaw, there have been some major casting shake-ups that have come to define the series. While the original cast of the CBS hit included Teddi (Robin Weigert) and Velma Bruin (Abby McEnany) as Colter's handlers, their quick exits from the series made for some surprising shifts in the show's overall fabric.
