The Tennessee Titans finally did what had been expected for so long. They fired special teams coordinator Colt Anderson after one year on the job. His replacement, John Fassel, has a long and productive history as an NFL special teams coordinator and looks -- by any measure -- to be a serious upgrade. ... Four other assistants are out or have moved on after their contracts were not renewed. One was passing game coordinator (defense) and cornerbacks coach Chris Harris, who arrived as part of Mike Vrabel's staff a couple years ago amid much fanfare. ... A week after Mike Borgonzi was hired as general manager, the Titans added two to their front office staff who have experience in that role. Former NFL general managers Reggie McKenzie and Dave Zieglers either give Tennessee an abundance of experience in roster-building and decision-making or they have too many cooks who ultimately will spoil the stew. ... The bulk of the Titans' personnel department spent last week at the East-West Shrine Bowl but did not see much of the main attraction, Colorado quarterback Shadeur Sanders. That does not mean they won't consider the son of a Pro Football Hall of Famer with the No. 1 overall pick.
