The start of the 2010 National Football League (NFL) season was certainly unusual, as anyone who tuned into the opening game can attest. Right before kickoff, players from the two opposing teams–the New Orleans Saints and the Minnesota Vikings–demonstrated solidarity when they walked onto the field holding up their index fingers and delivered a clear “we are one” message on national television.

The public display wasn’t necessarily a warmhearted gesture. Rather, it was a silent signal to NFL team owners that the players intended to stand their ground in the ongoing heated negotiations for a new collective bargaining agreement (CBA).
