I’ve watched every single NFL game Dan Marino played in and he never once did what Cam did.
I didn’t see what Cam did, but I saw Marino stand over a ball he’d just fumbled. He stood there and waited for someone else to cover it.
I also remember Marino trying to join some concussion lawsuit a couple of years ago, and I considered that ridiculous because he took so few hits. He withdrew from the suit a short time afterward.
