Dallas acquired the rights to quarterback Jack Concannon from Chicago on August 17, 1972 and sent Bill Line, Bob Asher and a 1973 second-round pick to the Bears. Concannon never appeared in a Cowboys regular-season game. Asher immediately became a multi-year Chicago starter, Line started on the 1972 defensive front, and pick No. 48 produced Gary Hrivnak. Chicago won the exchange decisively.
Chicago Bears Received

Trade Analysis
What Changed Hands
Chicago’s official trade history records an August 17, 1972 deal sending the rights to quarterback Jack Concannon to Dallas. The Bears received defensive lineman Bill Line, offensive tackle Bob Asher and the Cowboys’ second-round selection in the 1973 draft, pick No. 48. Chicago used that choice on defensive lineman Gary Hrivnak. The package gave the Bears two immediate veterans plus a premium future selection.
What Dallas Received
Concannon never produced a regular-season appearance for the Cowboys. NFL career records move from his 1971 Chicago season to Green Bay in 1974 without a Dallas entry. The Cowboys were acquiring contractual rights and a possible quarterback option rather than a guaranteed active-roster contributor, but the gamble ultimately yielded no regular-season playing value for Dallas.
What Chicago Received
Asher became the strongest immediate piece. NFL and Pro Football Reference records show him starting all 14 games for Chicago in 1972, 13 more in 1973 and all 14 in 1974 before a reduced role in 1975. Line also appeared as a starter on the Bears’ 1972 defensive front. Hrivnak, selected with the acquired second-round pick, appeared in 13 games as a rookie and 14 in 1974, starting seven that second season. Chicago therefore received value from every branch of the package.
Final Verdict
Chicago wins decisively. Dallas obtained rights that never became a Cowboys regular-season appearance, while the Bears gained a multi-year starting tackle, additional defensive-line help and a second-round selection that also contributed. An A- for Chicago and D for Dallas reflects a large realized-value gap. The Bears did not land a franchise superstar, but the depth and duration of their return overwhelmingly exceeded what Dallas received.
