It was not that bad of a call, given the current emphasis, as it looked like helmet to helmet at live speed, which is the only perspective the officials have.
They're told to side on caution and throw the flag if there is any doubt about whether helmet-to-helmet occurred. I'm open to the idea of making it a reviewable play, but doubt the league would go for it.
I'm not thrilled about the "kinder, gentler"'game either, but the politics surrounding concussions are slowly killing the foundation of the sport, as more and more parents are refusing to let their kids play the game due to all he hoopla surrounding the 10-15% of retired players suffering cognitive and/or psyhological issues.
