The New England Patriots made a move prior to the NFL playoffs that no one saw coming. The team signed veteran linebacker James Harrison after the Pittsburgh Steelers unexpectedly parted ways with the two-time Super Bowl champion.

With Harrison taking a backseat to rookie T.J. Watt in Pittsburgh and the consensus being that the linebacker's best days are behind him, the 39-year-old is fueled by the motivation to prove his doubters wrong as he heads to Super Bowl LII with his new team, via Kyle Hightower of ABC News.

“Anything people say I can't do, I want to prove them wrong,” Harrison said.

Although Harrison has only been in New England for a short time, the veteran has made an impression. Head coach Bill Belichick had nothing but high praise for the five-time Pro Bowler, via Hightower.

“This guy is a professional. He's into football. He's into his job and wants to do it well,” Belichick said. “I, 100 percent totally respect that. That's what you want from everybody.”

Harrison could be playing his last game in the NFL on Feb. 4 when the Patriots take on the Philadelphia Eagles in Super Bowl LII. It would be a fitting end to an incredible NFL career if New England were able to come out on top in this matchup between the league's elite.

The two-time All-Pro will make a strong case for the Hall of Fame when he's eligible. A third Super Bowl title would almost certainly assure his induction and at this point, the Patriots are heavy favorites to be back-to-back champions.
