New England Patriots great Vince Wilfork has lost a ton of weight since retiring from the sport five years ago, and his new slimmed-down physique absolutely stunned his former head coach Bill Belichick after seeing him recently.

Over his 11-year career with the Patriots, Wilfork was the epitome of a run stuffer. If an NFL scout were trying to create the perfect run-stopping nose tackle, the five-time Pro Bowler would be the prototype. At 6-foot-2 and at least 325 pounds, he was an absolute mountain in the middle of the Patriots’ defense line during their reign of terror through the league.

Wilfork’s success during his stint for the team is why he is being inducted into the organization’s Hall-of-Fame this week.
