The three true outcomes of the forward pass: completion, incompletion, interception. Also, sack. And strip sack. Roughing the passer. Pass interference and defensive holding. And offensive holding. Illegal hands to the face, offense or defense. Maybe the QB hits his thumb on the tackler’s helmet and has to be evaluated in the blue tent. Or hits his head on the turf. Or lacerated spleen. Let’s call it like thirteen true outcomes and see if the nerds can model it.
In all seriousness, I prefer that the NFL is a lawyer league rather than a VC/private equity league like MLB has become.
