First, I hope the injured player is okay. Anybody know?
What ever happened to the "head up-shoulder-wrap-up" technique?
Seems like DBs have pretty much taken this "chest high-punish" tackling technique which, in turn, leads to helmet-to helmet fouls (or at least constant really tough decisions for the officials). There seems to be no attempt to wrap up the runner/receiver in most of these instances. That said, too often, IMO, "targeting" or illegal helmet contact fouls are called as the result of a move the RECEIVER makes after or during the catch.
Now, as for the play, from what I saw, there was a catch, then a fumble into the end zone, a recovery by the defense, and then (probably) an IW. How did the play finally get adjudicated?
