Joe Sullivan (b

Denver and San Diego/Los Angeles Chargers agreed to a conditional or physical-dependent transaction involving 1977 draft pick (not exercised) and Joe Sullivan (b), but the raw record indicates the deal did not fully take effect as originally planned. Because the raw record describes the trade as voided, not exercised, or dependent on conditions that did not materialize, this row is best treated as a historical transaction note rather than a fully graded personnel exchange.
