The Colts traded guard Palmer Pyle to Minnesota in April 1964 for linebacker Steve Stonebreaker. Pyle spent the 1964 season with the Vikings, while Stonebreaker immediately became a regular for Baltimore, appearing in 14 games with 13 starts that year and ultimately logging 32 games and 19 starts for the Colts. Stonebreaker's stronger sustained role gives Baltimore the win.

Trade Analysis
The Exchange
In April 1964, Baltimore and Minnesota exchanged Palmer Pyle and Steve Stonebreaker. Contemporary reporting described the Colts sending Pyle to the Vikings for Stonebreaker, giving the transaction unusually strong period documentation. Both clubs received experienced players rather than draft assets, so the value can be measured by the roles each man held immediately after the swap.
Minnesota Vikings Return
Pyle provided Minnesota with a legitimate roster return during the 1964 season. That keeps the Vikings from receiving a poor grade, because the club did acquire an NFL lineman who suited up after the trade. His Minnesota tenure, however, was limited and did not develop into the same level of sustained starting value that Stonebreaker supplied Baltimore.
Baltimore/Indianapolis Colts Return
Stonebreaker quickly became a significant part of the Colts defense. He appeared in all 14 regular-season games in 1964 and started 13, then accumulated 32 games and 19 starts during his Baltimore tenure. For a direct player swap, that is a strong result: the Colts acquired someone who immediately handled a regular starting role on a contending roster.
Value in Hindsight
The difference is not that Minnesota received nothing; Pyle did provide short-term service. The separation comes from Stonebreaker's heavier and more sustained workload. A player-for-player trade is won when one side receives more useful snaps and starts without paying extra capital, and Baltimore clearly achieved that outcome once the post-trade careers are placed side by side.
Final Verdict
The Colts win, B+ to C. Minnesota gets credit for a functional one-season return from Pyle, but Baltimore acquired the more valuable player and immediately placed him in the starting lineup. Stonebreaker's 19 Colts starts provide enough durable evidence to move the deal decisively away from the earlier even assessment.
