This past Sunday we saw Super Bowl Lii come down to the wire and saw the Philadelphia Eagles come away with an upset win over the New England Patriots. This was the first ever Super Bowl win for the city of Philadelphia and they did so with back up quarterback, Nick Foles [VIDEO]. After a devastating loss, the Patriots [VIDEO] will look to regroup in the off-season, but not before their coaching staff drastically changes.

Coaching staff changes

As of Monday, February 5th, 2018 Patriots defensive coordinator, Matt Patricia was named as the head coach of the Detroit Lions.

"He spent six seasons as the Patriots DC and in that time frame, his defense never ranked outside of the top ten in scoring. He also won two Super Bowls in that same time frame" reports Edward Lewis from NFL.com.

This change brings question marks for the Patriots going forward concerning who will run their defense. In a report by Brad Crawford from 247sports, "Greg Schiano, defensive coordinator for the Ohio State Buckeyes is expected to replace Matt Patricia. Schiano is known for his aggressive style and this past year his defense led the nation in tackles for loss with 114 and was ranked second in the nation for total sacks with 45.

According to Edward Lewis from NFL.com, "Patriots offensive coordinator, Josh McDaniels was supposedly considering a head coaching position for the Indianapolis Colts, but a report from Pro Football Talk says he still might remain with the Patriots next season."

Is this the end for Rob Gronkowski?

Another report that has popped up after the Super Bowl was, "Could this be the end for Patriots tight end, Rob Gronkowski?" According to a report by Alex Marvez from Sporting News he says, "Rob Gronkowski declined to deny a report from Pro Football Talk’s Mike Florio that off-season retirement by the star New England tight end "would not shock me at all."

There are reasons to believe this could actually happen which starts with Gronkowski's history with injuries.

Alex Marvez reports, "These injuries date back to his college days at Arizona where he was forced to miss his entire junior season because of back surgery." Then from 2012 to 2016, he was unable to complete a full season because of a variety of torn ligaments and broken bones."

Even within the past couple weeks he suffered a concussion against the Jacksonville Jaguars and was just barely cleared to play in the Super Bowl. With all the injuries Gronkowski has gone through he says, "I'm going to sit down the next couple weeks and see where I am at." If the Patriots lose Gronkowski to retirement it may set them back a year or two and we may not see the same dominate Patriots as we have in recent years.
