James Curtis Wilder Sr. (born May 12, 1958) is an American former professional football player who was a running back in the National Football League (NFL) for the Tampa Bay Buccaneers, Washington Redskins, and the Detroit Lions.

Wilder played at Northeastern Oklahoma A&M College in Miami, Oklahoma, then attended and played college football at the University of Missouri where he led the Tigers to three bowl games and became known as the "Sikeston Train" and one of the most popular players for the program.

This resulted in one of the strangest plays in NFL history where the Tampa Bay defense simply stood still as the Jets ran the ball into the end zone; McKay was given a large fine from the league for that stunt.

Also in 1984, he set NFL records for carries (407) (later broken by Jamal Anderson then Larry Johnson) and touches (492) in a single season.

[3][4] Lawrence Taylor has stated that Wilder was one of the toughest running backs that he played against during his career.
