I can remember watching "Bootin' Ben" Agajanian kick against the Denver Broncos in the 1960s and having the feeling at the time that I could not believe I was seeing this. He had already been a legend for so long, and it was remarkable to actually see him perform.
What made me think about Ben Agajanian is the impending move of the Rams back to Los Angeles. And of course, they could be joined, in time, by the Chargers or the Raiders.
Not only is Agajanian still living -- he is 96 years old -- but he is the oldest player to have been with all three teams, along with several others.
