During his prime years with the Patriots, Wilfork was one of the best defensive tackles in the NFL. He made five Pro Bowls in New England and was a first-team All-Pro in 2012. The 35-year-old also helped the Patriots reach the playoffs on 10 occasions and win two Super Bowls before moving to the Texans in 2015.

While Wilfork accomplished almost everything he could on the field, he said Wednesday he still felt his NFL career will never be complete since his parents weren't able to see it. His mother, Barbara, died in December 2002, six months after his father, David Sr., died.

"They didn't get a chance to see their son live out a dream," he said, per Pro Football Talk's Michael David Smith. "Physically, that hurt every day—by the hour, daily. Not a minute goes by. But I know they had the best seat in the house. Thank you, David and Barbara Wilfork."
