The Giants have hired James Bettcher as their new defensive coordinator, a source tells Ian Rapoport of NFL.com (on Twitter). The former Cardinals DC also had an offer on the table from the Titans, but he turned them down. 
Bettcher was with the Cardinals since 2013 and spent the last three as DC. He was up for the Cardinals’ head coaching vacancy this offseason and even had the endorsement of Bruce Arians, but the gig ultimately went to Steve Wilks. Predictably, he had interest from multiple teams as a DC and he garnered two offers on the same day.
The Giants’ high-priced defense underperformed in 2017, finishing second to last in yards allowed and in the bottom third of DVOA. The Cardinals, meanwhile, allowed the sixth fewest yards in the league to opposing teams and had the fourth-best in DVOA in the NFL.
Bettcher’s arrival means that Steve Spagnuolo, the previous defensive coordinator and the Giants’ interim head coach for the final four games of the season, is out. At one point in time, it was thought that new head coach Pat Shurmur might keep Spags on board, but he’s opting to start fresh.
It’s not clear where the Titans and Mike Vrabel will go from here, but Packers cornerbacks coach Darren Perry has been mentioned as candidate for the DC vacancy.
I had thought I read somewhere that the Giants were going to be signing JDR as their DC? This is a good hire for them either way but I thought for sure that was who they would go with instead.
He was “the front-runner” but that was before it came out that new Cards HC Steve Wilks would be bringing in Al Holcomb as DC, freeing up Bettcher.
Spags should have been fired with McAdoo. It’s as much his fault for the defense quitting as it was the HC.

I’m good with this. We need a fresh start and a coach that will not take crap from his players.
