Detroit Lions and San Francisco 49ers
Even Trade Tier: minor
Confidence: medium
San Francisco 49ers received 1968 third round pick (#65-Lance Olssen) and 1969 fourth round pick (#86-Jim Sniadecki) from Detroit Lions for Dave Kopay. The recorded outcome does not show enough separation to identify a clear winner.
Miami acquired offensive lineman Lance Olssen from San Francisco for defensive back Tom Beier in May 1970. Olssen was released without appearing in a Dolphins regular-season game, while Beier likewise failed to make a regular-season appearance for the 49ers. Both players continued to have football transactions afterward, but neither produced NFL value for the club that acquired him in this exchange. With no realized return on either side, the trade is even.
