Somebody's getting fined, I'd guess. Doesn't mean they're wrong, though. They are wrong. It's a pretty easy rule to follow. The launching and the initial contact being made with the helmet and/or to the opponents helmet are really easy to not do. http://www.nfl.com/videos/nfl-videos/09000d5d81b80962/Player-safety The video also shows a hit by Ray Lewis where he was in the exact same situation as Harrison on Massaquoi, and similar to Robinson on Jackson. Lewis hit the receiver in the chest, with his shoulder. Lewis still made a highlight reel hit and defensive motivating play. Dustin Keller still did not catch the ball. Keller was still hurt, but was able to play the next week. I think the video is quite clear. Shoulder in chest: OK. Helmet to helmet: not OK. However, what I do wonder is how much control the defender actually has. These guys are moving fast, and changing positions fast. What if someone intends to hit his shoulder into the chest but ends up hitting his helmet into the head? How much control does the defender have when things are moving so fast? I don't have an answer to this question, as I've never played tackle football with 250 pounders who could run 4.5 40's.
