Looney was selected in the first round with the 12th overall of the
1964 NFL draft by the
New York Giants. He was also selected in the sixth round of the
1964 AFL draft by the
Kansas City Chiefs, but chose to play in the NFL instead. He was with the Giants just 25 days before they traded him along with offensive lineman
Lou Kirouac to the
Baltimore Colts for wide receiver
R. C. Owens and safety
Andy Nelson during training camp on August 24, 1964. As a member of the Giants, Looney racked up a number of fines for violating team rules. He put together one good season, racking up 114 carries for 356 yards and five touchdowns. While with Detroit, Looney was told by coach
Harry Gilmer to carry in a play to the quarterback. Looney refused and told Gilmer, "If you want a messenger boy, call
Western Union." Detroit traded Looney to the
Washington Redskins, where he had an uneventful tenure. He had 55 carries for 178 yards. The only highlight of his time with the Redskins came on a play in which he did not even have the ball. He was pass protecting for quarterback
Sonny Jurgensen, and ended up leveling an onrushing pass rusher with a right hook to the jaw. When he tried to renegotiate his contract, he was let go. He would often intentionally run the wrong way on plays in practice in order to make things more challenging for himself. He once skipped several practices. When questioned about his absences, he responded by saying, "If practice makes perfect and perfection is impossible, why practice?" ==After football==
