1972 Dolphins great Larry Csonka celebrates as 49ers, Eagles lose

Larry Csonka and the rest of the 1972 Miami Dolphins stand alone as undefeated, still

It is an annual rite. The final NFL team absorbs its first loss and the 1972 Miami Dolphins celebrate.

On Sunday, the San Francisco 49ers and Philadelphia Eagles fell for the first time in 2023.

That means no more undefeated teams and Larry Csonka took to Twitter for a toast. Csonka was a star running back on the 1972 Dolphins, you know, the lone undefeated team in NFL history.
