He played college football for coach Barry Switzer and the Oklahoma Sooners as a halfback out of the wishbone offense.
One of Overstreet's great moments as a Sooner happened on October 4, 1980 when the senior halfback ran for 258 yards on 18 carries against the Colorado Buffaloes as Oklahoma won big, 82-42.
A contract dispute with the Dolphins led him to sign with the Montreal Alouettes of the Canadian Football League, who, under the ownership of Nelson Skalbania, tried to buy a big money winning team.
He was driving northbound in his 1980 Mercedes on Texas State Highway 155, when his car swerved off the road about 10 miles northeast of Tyler into gasoline pumps at a service station and exploded.
[2] The Dolphins wore a helmet decal with the number 20 in his memory during their 1984 season in which they reached Super Bowl XIX.
