I like that PI not being called. It was the only way the defender could make the play. He has to jump up like that against a 6'5 TE. Gronk never got that call. Why should anyone else?
The unstoppable offense of Baltimore has scored just 17 points to this point, even with the fumble that gave them a short field early on. So people bagging on SF about what they're doing should probably take a step back, for at least the moment.
