New England Patriots coach Bill Belichick had his share of downs from last NFL season, a reason questions of which surfaced after the Pats fell to the Philadelphia Eagles at Super Bowl LII, 41-33.

This is despite the fact that the Patriots finished the regular season with an AFC best 13-3 that allowed them to extend their Super Bowl appearance to a record 10 times and their third in four years. The Eagles were the underdogs in the playoffs, especially with Carson Wentz taken out with a season-ending injury.

Now, the Pats are at it again. As of writing, they are leading the AFC once more with a 9-3 record despite a lot of anxious moments, with Belichick and Tom Brady not exactly having a smooth relationship. Tension from within had been building in New England. That includes a claim that Brady had wanted a "divorce" from Belichick because the 41-year-old quarterback is allegedly considering to walk away from football and the Patriots, CBS Sports reported.

But in the NFL, dark moments can change quickly. It is perhaps the best way to put it with Belichick seeming reinvigorated this season. The Pats are primed for yet another playoff run, easily shrugging off the belief that the 66-year-old's magic is fading, NESN pointed out.

And just like that, most feel that Belichick is good for another four to five years at the helm. This is in spite of him already being feted as one of the greatest coaches of the game.

“You got the sense that maybe a couple more years, maybe he gets to an even 20 and walks away after the 2019 season. I’m not getting that sense at all anymore. You talk to people in that building this year, the tension of last year is gone. The relationship with Brady isn’t perfect, but it’s a lot better than it was last year. And there are people I talk to there that think he could go another four or five years easy based on how energized he’s been this year, based on how passionate he is about his job," said MMQB’s Albert Breer on Fox Sports 1.

It remains to be seen if Belichick can make up for the Super Bowl LII downfall. It is a brand new season and some issues seem to have been mended. At any rate, the Patriots seem to be running on all cylinders, hopefully smoothly until Super Bowl LIII, which happens on Feb. 3, 2019 at the Mercedes-Benz Stadium in Atlanta, Georgia.
