Ya, that’s my Pittsburgh Steeler offensive lineman’s number and uniform design of 1966 and 1967 only. Take your pick. They’re both identical and referred to by the ballplayers that had to ware them as the “Batman” jerseys. I, instead, liken them to the first “Star Trek” uniforms. The out of register imagery is meant to suggest movement. We offensive linemen get little or no respect playing that position. Like we’re in the foreground of the formation but the background of the fans’ mind. As I asked in my book, what football fan can name me a half-dozen pro football Hall of Fame guards that played before they started paying respectable money? I’m sorry, I can’t hear you.  (Are you aware that offensive linemen sustain more concussions than any other position in football)?
