(1) From all indications, Franco was a marvelous human being. He embraced Pittsburgh as much as Pittsburgh embraced him.
(2) Franco flew under the radar when he was drafted. At Penn State, Lydell Mitchell was the main attraction, and Harris played second banana.
(3) The great Steeler teams of the 70's were largely the product of effective use of anabolic steroids - before other teams caught on. Those linemen got "great" in the weight room - Mean Joe being the exception. He conspicuously couldn't bench press much more than his own weight. The other linemen were benching 500 lbs plus.
(4) Franco Harris wore out his welcome in Pittsburgh before he departed and retired. The marvelous runner who used to break tackles in his early years was dropping like a sack of potatoes on first contact, or running for the sidelines when he was under assault. But "we" forgave him for that.
(5) Pittsburgh traditionally names its bridges after prominent PIttsburghers (e.g., the Roberto Clemente Bridge, leading to PNC Park). There is a movement to name the Fern Hollow Bridge, which famously collapsed last year and will shortly be re-opened, as the Franco Harris Bridge. It would be a nice tribute; it's in a beautiful part of town.
