New England Patriots head coach Bill Belichick might be the best in the NFL at plugging new people in his system and not missing a beat.

In his years as the coach, Belichick always seems to know when to let one person go before they lose their value and putting someone else in at the position and the team continues to run as usual. The same might go for coaches with Matt Patricia leaving New England to take over as head coach of the Detroit Lions and Brian Flores becoming the new defensive coordinator.

Devin McCourty has been a staple of the Patriots defense and doesn't see many changes with Flores now in charge. Dont'a Hightower had said the Patriots defense is faster under Flores and McCourty doesn't agree with that.

“I mean, it’s always going to be different because somebody else is calling it, you know what I mean,” McCourty said, via Pro Football Talk. “He’s not going to be the same as Matty P, but our defense is kind of the same, you know what I mean — like we don’t have a whole new defense because Flo’s been in this system for years. It’s a lot of crossover.”

Flores moved up from being a linebackers coach to the defensive coordinator, and he does have some new guys to work with. McCourty's brother Jason joined the Patriots and should have a significant role with the team especially since Malcolm Butler moved onto the Tennesee Titans.

The Patriots are just kicking off training camp, and everyone should get a real feel about this defense in the next few weeks.
