You know, I had nearly forgotten about this little fact. Swann was well known for his amazing catches and leaping ability, but the tale of him jumping over a car in 1979 is almost never told. I’d seen it at some point in my youth, but never on the Internet before.
Wexell had a mention of it in his book Tales From Behind The Steel Curtain. You can see it at the bottom of this page.
Enjoy this absurd Steelers happening, and go talk about it with someone who has no idea about it.
