After a 10-3-1 season, the
Kansas City Chiefs held the 23rd overall pick late in the first round of the
1972 NFL draft when they used it to select Kinney. The running back was the second of three Nebraska Cornhusker teammates selected in the first round;
QB Jerry Tagge was taken 11th by his hometown team, the
Green Bay Packers, and
DT Larry Jacobson was selected by the
New York Giants with the 24th pick, immediately after. On an unfortunate note, this draft class is often recalled in a poor light by sports historians as the worst in its modern history. Kinney would not have to wait long both to hit the field and to reunite with teammates as he made his NFL debut as Kansas City faced the New York Giants in the Hall of Fame Game to kickoff the 1972 NFL preseason. In the third week of the preseason, Kansas City's
Arrowhead Stadium opened its gates for the first time and local newspapers highlighted the chance to see the college star transition to the professional game. Kinney found a place in the regular line-up by the start of the regular season, starting in weeks 3 and 4, before injuries sidelined him for three games mid-season and again in December with the Chiefs placing him on injured reserve to finish the season. For most of his time in Kansas City, Kenney would serve as a blocking back or injury substitution for
Ed Podolak. In his fourth season, he eclipsed Podolak in terms of number of starts, but still accrued fewer carries than the latter. Kinney also lagged behind the starting fullbacks,
Wendell Hayes and
Woody Green, in carries, yards and touchdowns each year. Kinney was picked up to replace the injured Jim Braxton as the blocking back for
O. J. Simpson. A few weeks after being waived, Kinney gained 114 yards against the Chiefs. Kinney was waived by the Bills in August
1977, and retired. After football, he worked in financial services. ==NFL career statistics==
