LOL, I'm not arguing the hit was OK because of a technicality... the people that are arguing that he should have been flagged for it are arguing that based on a technicality.
I have zero issue with the hit or not calling a penalty on the hit. Why? Quite simple really... I have simply no earthly idea what anybody really thinks Sherman should have or even could have done differently there. He's clear of the holder by the time the whistle is blown. You're committed at that point.
This isn't the Matrix and Sherman isn't Neo. He's not stopping his progression or his body within a second of impact because he hears a whistle. Just not realistic for somebody to expect him to do that.
Having been around these boards long enough, I can also say for 100% certainty that if Sherman played for the Ravens, it would be unanimous that it shouldn't be a penalty, and if Tucker were the kicker, it would be unanimous that it should be. The only differences here are the jerseys they are wearing.
If you don't want that play to happen, blow the whistle when its time to blow the whistle. Don't wait until he's 3-4 yards into the backfield to try to stop progression of fully grown, highly athletic athletes. Its not happening.
The first audible whistle on the TV broadcast (https://www.youtube.com/watch?v=kxiKnrUK_6o) happens well after Sherman hits the kicker.
