Titan fans NOT happy about the no call on the forced fumble

I've already posted this in this thread, but I'm going to post it again.

The hit was legal. Not just because the defender lead with his shoulder, but also because the receiver was no longer considered defenseless. He had taken 3 steps and lowered his head to brace for the hit... that means he had become a ball carrier/runner and contact with his head is no longer illegal as long as it's not helmet to helmet.
