The Cardinals signed a cornerback Monday -- Lou Young, who has been around since 2014 and has had stints with the Panthers, Broncos, Ravens, Redskins and Jaguars. Much of the time was spent on practice squads, and he was with Washington in the 2017 preseason before he was released and did not play anywhere else during the season.

But Young did play six games for Carolina in 2016, when Steve Wilks was the defensive backs coach, and he was with Carolina in 2015 as well. And his arrival is a reminder of how chunks of the roster often look when a new coach arrives -- it's never a surprise to see a few friendly faces brought in. It's a natural move. When possible, coaches want to know what they are working with.

When Dennis Green was hired, one-time Vikings like cornerback Robert Tate, offensive lineman Everett Lindsay and wide receiver Chris Collins all spent at least some time in Arizona that first season. Ken Whisenhunt had guys like wide receiver Sean Morey, punter Mike Barr and tight end Tim Euhus. Bruce Arians had Drew Stanton and Jerraud Powers.

Again, it's not necessarily a big chunk of the roster, and it doesn't mean the Cardinals will chase lesser players just because they have a tie to a coach on staff. But as with most places of work, familiarity helps.
