Dallas Cowboys received Herb Adderley from Green Bay Packers,…

The Exchange

On 1970-09-01, Dallas Cowboys and Green Bay Packers completed a deal in which Dallas Cowboys received Herb Adderley, while Green Bay Packers received Malcolm Walker and Clarence Williams (b. 1946-09-03). The comparison centers on what each original club actually obtained from the exchange. Later moves matter only when they identify the value attached to an asset that changed hands.

Dallas Cowboys Return

Dallas Cowboys received Herb Adderley from Green Bay Packers, sending Malcolm Walker and Clarence Williams (b. 1946-09-03) the other way. Clarence Williams is currently mistyped as a pick and must be corrected to a player before an even high-grade verdict. That outcome supports a A- grade for Dallas Cowboys, and the overall verdict is Even Trade.

Green Bay Packers Return

Green Bay Packers received Malcolm Walker and Clarence Williams (b. 1946-09-03) from Dallas Cowboys, sending Herb Adderley the other way. Clarence Williams is currently mistyped as a pick and must be corrected to a player before an even high-grade verdict. That outcome supports a A- grade for Green Bay Packers, and the overall verdict is Even Trade.

Value in Hindsight

Green Bay's official Herb Adderley history says Dallas acquired the Hall of Fame cornerback for center Malcolm Walker and rookie defensive end Clarence Williams. Adderley helped Dallas win Super Bowl VI across three seasons, while Williams became a long-term Packers starter and Walker also contributed, creating substantial value on both sides. Clarence Williams is currently mistyped as a pick and must be corrected to a player before an even high-grade verdict. If a draft choice was moved again, the later trail can explain what the original consideration became, but unrelated success after another transaction is not credited twice. Where one historical detail remains uncertain, the evaluation uses the strongest supported description instead of filling the gap with speculation.

Final Verdict

The final call is Even Trade. Dallas Cowboys receives A-, while Green Bay Packers receives A-. Neither original club created enough separation in direct value to justify a winner, so equal grades fit the evidence. The grades remain proportional to the size and certainty of the exchange, rewarding real value while keeping a measured distinction between a clear edge and an overwhelming win.
