I don't know how anyone can say one way or another whether or not those rumors were true?
It's strange to me when people insist that they know for a fact that Dan Marino used cocaine while the Pitt because their cousin's girlfriend's uncle's mailman saw him do it at a party in Oakland one night.
No, you don't know that.
Here is what we do know: he never failed a drug test in the NFL and he played in Miami – America's cocaine capital. Also, he and his college roommate, Jimbo Covert, have always adamantly denied the rumor. I can see why he would deny it coming out of college - or even during his playing days - but why now?
Here is what I think happened: after lighting up college football over the previous three seasons, Marino had a horrible senior year under new coach, Foge Fazio. Also, there were rumors not only of drug use but also that maybe he wasn't the most coachable kid in the world.
He may have also used some recreational drugs but in the early 80s that was not uncommon. A lot of our national leadership and people who might otherwise surprise you also used recreational drugs during that epoch.
The Steelers passed on him because they did not realize that Bradshaw was done. That is probably the biggest drafting mistake in the history of the Pittsburgh Steelers.
I did once hear through the grapevine that Penn State used to use that in recruiting against Pitt. They would tell parents that Oakland was dangerous and that half the Pitt football team was on drugs.
I would bet anything that was the genesis of those rumors.
However, I also know that misinformation is a big part of the NFL draft experience and it would not surprise me if we were to one day learn that the Miami Dolphins were also pushing that rumor in the hope that the talented young quarterback might slip to them at pick no. 27.
