Napa's style is much the same imo, he even seems to lose vision of the what the ball carrier is doing once he does commit.
it may be only the second time he has knocked out someone with his head in x amount of tackles but i recall him being in trouble for the same technique ending in shoulder to head contact a few times aswell so i think he has something to fix. some may think its an accident but its clear it aint gonna be treated that way so its gonna be on him to make sure it doesn't happen again.
