He went on to play basketball at Iowa State University, before focusing on football after his sophomore season and proceeding to lead the team in receiving for 3 consecutive years.
Six of the receptions for 140 yards and both touchdowns came in a single Monday Night Football game against the St. Louis Cardinals while replacing an injured Warfield.
In 1973, he was having a Pro Bowl type season starting opposite to Bob Hayes, but suffered a broken ankle in the seventh game against the Philadelphia Eagles, that placed him on the injured reserve list and would hamper him for the rest of his career.
Even though he was starting for the Cowboys, he wasn't happy with his contract, so he was traded to the Denver Broncos for a third round draft choice (#75-John Smith) on September 5, 1974.
On May 6, 1975, he was traded along with a sixth round draft choice (#156-Art Best) to the Los Angeles Rams, as compensation for signing free agent Phil Olsen.
