I had so many puns about the first female NFL referee that I wanted to use here, but ABC News beat me to all of them.It's a shame that Shannon Eastin had to cross a picket line to make history, but well-behaved women rarely do. I'm just hoping her success breaks barriers for other women to prove themselves on the field in the future.She'll take the field again on Sunday, Sept. 9 to referee the Lions-Rams game if the lockout between the league and the NFL Referees Association doesn't end … and I will watch my first NFL football game since the Steelers won the Super Bowl in 2006. Pittsburgh represent!
