Robinson, a college football player, signed a contract on December 2 with the Detroit Lions, a pro football club. The contract was a standard form that contained a clause stating, "This agreement shall become valid and binding upon each party only when and if it shall be approved by the League Commissioner." In late December, Robinson informed the Detroit Lions that he would not be playing for them because he had signed on with the Dallas Cowboys. On January 12 the commisioner approved the contract. Detroit then sued Robinson for breach of contract. Was there ever a contract between Robinson and the Detroit Lions? why or why not?
