Danson will be replacing Peter MacNicol who played FBI Assistant Director Stavros Sifter and supervisor of Special Agent Avery Ryan (Patricia Arquette.) D.B. Russell (Danson) and Special Agent Avery Ryan, already have a history together as CSI: Cyber was introduced in an episode of CSI last season.
I've already spoken about how I was disappointed in CSY Cyber. I love Patricia Arquette and I actually like Ted Danson in CSI, so my hope is that the addition of him plus the other changes (tweaks) that are expected will help improve the show.
