The OC called 2 incredible plays that had both Conner, and Grimble wide open for 3rd down conversions, and the both fumble. That's not on the OC.
Plus the first call of the second half had JuJu wide the **** open, and Ben missed him. Ben then over threw a wide open Washington. There were a ton of missed opportunities in this game, even with the TOs, the Steelers were on the goal line with a chance to win. That RPO call was a head scratcher though, but I'm not faulting him for Ben throwing to a double covered AB.
AB misses a wide open receiver as well on his pass.
