Why can't it still be a judgment call, just with the assistance of replay? The entire goal here is to eliminate obvious, blatant mistakes. If the ref takes a look and judges it to be PI, they throw a flag; if he judges it not to be PI, he doesn't. Just because they are using replay doesn't mean they have to go frame by frame, or by the letter of the rulebook, IMO.
I can't believe I am defending the NFL so much on this, but I just feel like these issues are being overblown and will sort themselves out, like @nattysez articulated a few posts up.
What’s next, holding and if not, why not?
*If the tight end or tackle had not held, the rb would not have cleared the edge and scampered in for a TD.*
Most of us share the goal. The problem here is taking a quintessential judgment call and imposing another level of judgment.
